PyInstaller and error: 'support/loader/run'

2011-03-30 Thread Ale Ghelfi

I've a script of Python 2.6.6 under Ubuntu 10.10 and i would pass it to 
XP like exe.
My script use wxPython and read some files jpg that are in the same 
directory of the script.


Before to use Pyinstaller 1.4, i did:
cd /source/linux
python Make.py
make

But "make" returned this error that i didn't understand:

gcc -pthread  -I/usr/include -I/usr/include/python2.6 -I../common 
-DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing

-c getpath.c -o getpath.o

getpath.c:40: fatal error: osdefs.h: File o directory non esistente
compilation terminated.
make: *** [getpath.o] Errore 1

Anyway, after this, i did also:
python Config.py

Then:
python makespec.py -F -w MioScript.py
python Build.py (il file ottenuto dal passaggio precedente)

After Build.py, pyinstaller return this error:

I wouldn't have a problem with it.

I would also like to react to the following.

Guido van Rossum in msg95975 on http://bugs.python.org/issue1771 wrote:
| Also, for all of you asking for cmp back, I hope you realize that

This is a play on semantics. If you need python code to compare
two items, then this code will be called N log N times, independently
of the fact how this code is presented, as a cmp function or as rich
comparison methods. So forcing people to write a key function in cases
where this will only result in the cmp code being translated to __lt__
code, accomplishes nothing. 

As far as I can see, key will only produce significant speedups, if
comparing items can then be completly done internally in the python
engine without referencing user python code.

My rule of thumb is that a < b is equivallent with cmp(a, b) < 0

But what does this have to do with use cases? Does what is reasonable
depend on the current use cases without regard of possible future use
cases? Is the conflict between key and cmp a lesser problem in the
case of someone having a huge data set to sort on a computer that lacks
the resources to decorate as opposed to currently noone having such
a data set? Are we going to decide which functions/methods get a cmp
argument depening on which use cases we currently have that would need it?

This thread started with a request for use cases. But if you take this
kind of things into consideration, I don't see how use cases can then
make a big difference in the final decision.

Re: delete namespaces

2011-03-30 Thread Jean-Michel Pichavant


monkeys paw wrote:

How do i delete a module namespace once it has been imported?

I use

Then i make a modification to banner.py. When i import it again,
the new changes are not reflected. Is there a global variable i can
modify?

It depends on what you want to achieve.

1/ if you want to re-import your module because it contains User data 
that may have been updated, one way is to make sure all you definitions 
are at the module level and use the execfile statement. ofc the file is 
executed, so it can be done only in a trusted environment.


2/ if you want to reload your module because you changed the code and 
want to test it, the best way to do it is to write a test file that will 
do all the tests so that restarting the test is cheap. Testing from a 
newly created python process is always the best solution, if available.


3/ if you want to do the 2/ but require a painful long prologue to your 
test, then you may want to use the builtin reload. Use it with care, 
because any existing object created from the previous module will not be 
affected, they'll still hold the previous code. "reload" solves some 
problems, but bring others, especially for the newcomer.

Not sure if this can be redone as a one-liner; currently it's two.


for i in range(3):
print '\n\t"'+("minor","medium","major")[i]+'
":({\n\t\t'+"\n\t\t".join([q[0]+',"'+" ".join(q[1:])+'",' for q in
[q.split("\x96")[-1].split(" ") for q in "\n".join([q.split("

a.split("\n")]).replace("\x92","'").split("\n")] if
q[0]!="\x97"])+'\n\t}),'

That's the code I used in IDLE to translate this:

into something that my dice-roller can use. (In the interests of

You can set the current figure to fig1 with the following:

figure(fig1.number)
plot(...)

Alternatively, you can use the plot methods of a particular axes:

fig1 = figure()
ax1 = axes()
fig2 = figure()
ax2 = axes()

ax1.plot(...)
ax2.plot(...)

It works the same for subplots:

fig1 = figure()
ax11 = subplot(211)
ax12 = subplot(212)
fig2 = figure()
ax21 = subplot(211)
ax22 = subplot(212)
 
ax12.plot(...)

Java and languages in Microsoft's CLI (common language infrastructure) are 
statically typed, so it's not exactly a straight-forward comparison. 

IIRC, IronPython programs compile to a DLR (dynamic language runtime) AST 
(abstract source tree). This represents the program as runtime method calls and 
invoked DynamicSite objects. A site creates a caching delegate that checks the 
given argument types. As it encounters new combinations of argument types, it 
compiles the operation and updates the delegate.

Each room is a method of Game. The returned value of each room is a reference 
to another room, depending on some condition. play() just loops the following: 
call room(); store the return reference as next; assign next to room. This 
continues until death(), which randomly insults you and quits.

You don't have a · character. Your computer doesn't understand
"characters". You have the byte sequence \xc2\xb7. When you have a
Unicode string (the default in Python 3), Python needs some way of
converting the byte sequence to a character sequence. The way it does
that is through the encoding. But you don't have an encoding
specified, so rather than guess, Python is falling back on the lowest
common denominator: ASCII, which doesn't understand the byte \xc2-
hence the error.

To fix this, just put the line
# coding=utf-8
at the very top of the code file.

A middle dot is Unicode \x00\xb7, which maps to UTF-8 \xc2\xb7. According to 
PEP 3120 the default source encoding for Python 3.x is UTF-8. (I'll take their

(e.g. # coding: ascii)? If not, are you sure that you're running in 3.x?

Get USB ID of a serial port through pyserial?

2011-03-30 Thread John Nagle


  Is there some way to get the USB ID of a serial port through
pyserial on Linux and/or Windows?  USB serial port devices have
device names determined by when they were plugged in.  So, if
you have more than one USB serial device, you need the USB device's
built-in ID to figure out what's out there.

  Is there a way to get that info portably?

FBI wants public help solving encrypted notes from murder mystery

2011-03-30 Thread Joe Snodgrass


FBI cryptanalysis hasn’t decrypted notes from 1999 murder mystery

http://tinyurl.com/4d56zsz

The FBI is seeking the public's help in breaking the encrypted code
found in two notes discovered on the body of a murdered man in 1999.

The FBI says that officers in St. Louis, Missouri discovered the body
of 41-year-old Ricky McCormick on June 30, 1999 in a field and the
clues regarding the homicide were two encrypted notes found in the
victim's pants pockets.

The FBI says that despite extensive work by its Cryptanalysis and
Racketeering Records Unit (CRRU), and the American Cryptogram
Association, the meanings of those two coded notes remain a mystery
and McCormick's murderer has never been found. One has to wonder
though, if the FBI can't figure this out, who can? But I digress.

>From the FBI: "The more than 30 lines of coded material use a
maddening variety of letters, numbers, dashes, and parentheses.
McCormick was a high school dropout, but he was able to read and write
and was said to be 'street smart.' According to members of his family,
McCormick had used such encrypted notes since he was a boy, but
apparently no one in his family knows how to decipher the codes, and
it's unknown whether anyone besides McCormick could translate his
secret language. Investigators believe the notes in McCormick's
pockets were written up to three days before his death."

"Standard routes of cryptanalysis seem to have hit brick walls," said
CRRU chief Dan Olson in a statement. To move the case forward,
examiners need another sample of McCormick's coded system-or a similar
one-that might offer context to the mystery notes or allow valuable
comparisons to be made. Or, short of new evidence, Olson said, "Maybe
someone with a fresh set of eyes might come up with a brilliant new
idea."

The FBI says it has always relied on public tips and other assistance
to solve crimes though breaking a code may represent a special
circumstance.

Hi all,

Sorry for the late post this week. The next meeting is next Monday,
the 4th of April at RMIT.

The room has changed! After the double-booking last week we've been
moved to 12.07.02 (building 12, level 7, room 2).

Tennessee's going to talk to us about an approach to benchmarking that
he's been working on.

If you have some experience with benchmarking or profiling Python
code, perhaps you have something you can share?

I'm going to talk about PyWeek number 12, which starts this coming
Sunday morning :-)

Dictionary Descriptors

On the python-ideas list, someone made a wild proposal to add
descriptors to dictionaries.

None of the respondents seemed to realize that you could (not should,
just could) already implement this using hooks already present in the
language.  I'm posting an example here because I thought you all might
find it to be both interesting and educational.

For more details on how it works and how it relates to descriptors,
see http://mail.python.org/pipermail/python-ideas/2011-March/009657.html

Raymond

 sample code 

class MyDict(object):
def __init__(self, mapping):
self.mapping = mapping
def __getitem__(self, key):
value = self.mapping[key]
if hasattr(value, '__get__'):
print('Invoking descriptor on', key)
return value.__get__(key)
print('Getting', key)
return value
def __setitem__(self, key, value):
self.mapping[key] = value

class Property:
def __init__(self, getter):
self.getter = getter
def __get__(self, key):
return self.getter(key)

if __name__ == '__main__':
md = MyDict({})
md['x'] = 10
md['_y'] = 20
md['y'] = Property(lambda key: md['_'+key])
print(eval('x+y+1', {}, md))

 output 

Getting x
Invoking descriptor on y

Sure, here are three one-liners using itertools.groupby() to emulate

  sort letters | uniq -c# count unique values
  sort letters | uniq -d# find duplicates

>>> from itertools import groupby

P.S.  Of course, there are many ways to do this.

It might help show calling patterns if you added print statements to
the while loop:

   def play(self):
next = self.start
while True:
room = getattr(self, next)
print "--- Calling the method:", room, "---"
next = room()

I asked Guido about this once and he said that he didn't
consider them to be part of the core.  He worried that
they would be overused by beginners and they would be
a distraction from learning plain, simple Python which
doesn't often need either copy() or deepcopy().

AFAICT, he was right.  I've seen large projects where
deepcopy and copy where not used even once.

I think it's uncommon for an application to be programmed entirely in Python. 
It's common to use C/C++ to accelerate performance critical parts of the code. 
I don't see that as a weakness of Python. The developer uses whichever tools 
work best for the task at hand.

Calibre is a popular e-book manager/converter created by Kovid Goyal. It's

running Python2 Python3 parallel concurrent


Greetings,

The purpose of this communique is to document a process for 
installing python2.7.1 in parallel with python3.2 on a concurrent 
desktop with independent idle and python path structure.


Each version (python2, python3) will be installed in a separate 
python shell (idle) run on a separate local install so that both 
versions are running side-by-side on the same user desktop, each python 
shell having a unique .idlerc(v) configuration dir for look&feel as well 
as separate recent files lists and separate working .py folders.


Neither of the installs should affect the other installation (nor 
idle operation), nor should the installs affect the system-wide default 
install (python2.6.2 in my case running ubuntu 9.04 jaunty). As well, 
the search paths should not overlap except at the top $HOME level. The 
over-all purpose is to be able to play with both versions together in 
order to facilitate/enable/solve concurrent development, migration, and 
debug issues between the two versions.


I trust that if the community has already solved this problem, and 
has a better way, that I may discover it and be able to adopt it to my 
own environment as well.


If you find any mistakes, please let me know.

Best regards, m harris.

The primary unordered issues for solution(s) are:

1) separate PythonX folders for .py files, $HOME/PythonX
2) separate desktop launchers to cleanly launch idleX for pythonX
3) separate .idlercX files in the home dir for IDLE pythonX
4) separate correct $HOME/local/pythonX installation folders
5) separate correct $HOME/bin/ launch scripts and sym links
6) Config from sources with correct --prefix setting
7) Local Build & Install

===
BUILD VERSIONS FROM SOURCE
===
Download the 2.7.1 and 3.2 tarballs from here:

http://www.python.org/download/

From your $HOME directory create the modules (.py) folder with:

mkdir Python3 ie.,  $HOME/Python3/

 and then create the local installation folder in $HOME/local:

mkdir local
cd local
mkdir python3 ie.,  $HOME/local/python3/

Create a $HOME/bin/ folder, if it does not already exist.

Unpack each tarball in $HOME with:

tar -xvf Python-3.2.tar.bz2 --bzip2

cd Python-3.2and then build & install with:

./configure --prefix=$HOME/local/python3
make
make install

NOTES:  Repeat these steps for each local version. It is important 
that the development headers already be installed, including the tk-dev 
package so that tkinter mod will get built enabling idle. The tarballs 
are available in several compression schemes... I chose bzip2.
The --prefix option tells the installer where pythonX will live; 
this will be a local install visible only to the development user.


===
Symbolic link(s)
===

Create a symbolic link for python in $HOME/bin/ with:

cd $HOME/bin/
ln -sf $HOME/local/python3/bin/python3 python3

note:  (python3 can now be invoked from a linux terminal)

   Repeat the steps for each version.

   You may need to set your linux path to include
   $HOME/bin/  in either .profile or .bashrc if not
   already in place. This is usually already set on
   most modern linux distros if ~/bin/ exists.

===
Launcher Scripts
===

Create the bash launcher script used for setting the
PYTHONPATH and starting the python3 script. Use a text
editor of your choice to create a text file in $HOME/bin/
called  Python3-IDE  containing these three lines:

#!/bin/sh
export PYTHONPATH=$HOME/Python3
exec $HOME/bin/idle-python3 -n

Now, create the python script for importing and launching
the PyShell from idlelib; use a text editor to create a
text file in $HOME/bin/ called  idle-python3  containing:

#!/home//bin/python3

from idlelib.PyShell import main
if __name__ == '__main__':
main()

The first line /home// is $HOME, but may have to
be spelled out in the script above. Now, set both scripts
executeable with:

chmod 0754 $HOME/bin/Python3-IDE
chmod 0754 $HOME/bin/idle-python3

Notes:  Repeat for each version. Summary; each version will
have its own launcher script ( PythonX-IDE ) and each will
have its own python idle starter script ( idle-pythonX ).

The launcher script is the 'called' file from the Desktop
launcher icon, which sets the PYTHONPATH. The python idle
starter script correctly starts the interpreter and then
initiates the PyShell (python idle shell) import main and
run.

No other information about the guy? It might help. If the note is of any use 
then people and places would be in it. If that is the case then it would 
help to know where he lived and some of the names of people he knows.


The note seems like it may not be just encrypted but a sort of 
compression(or rather shorthand/jargon) was used. Was the guy a drug dealer? 
It could be a list of "clients" or information about where he sold drugs(the 
numbers look like street addresses or amounts.


If these kinda notes were so common from this guy then surely the FBI should 
have many more?

Re: Guido rethinking removal of cmp from sort method

Incorrect. You don't even need megabytes of data to see significant 
differences. How about a mere 1000 short strings?

[steve@wow-wow ~]$ python2.6
Python 2.6.6 (r266:84292, Dec 21 2010, 18:12:50)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from random import shuffle
>>> data = ['a'*n for n in range(1000)]
>>> shuffle(data)
>>> from timeit import Timer
>>>
>>> t_key = Timer('sorted(data, key=lambda a: len(a))',
... 'from __main__ import data')
>>> t_cmp = Timer('sorted(data, cmp=lambda a,b: cmp(len(a), len(b)))',
... 'from __main__ import data')
>>>
>>> min(t_key.repeat(number=1000, repeat=5))
0.89357517051696777
>>> min(t_cmp.repeat(number=1000, repeat=5))
7.6032949066162109

That's almost ten times slower.

Of course, the right way to do that specific sort is:

>>> t_len = Timer('sorted(data, key=len)', 'from __main__ import data')
>>> min(t_len.repeat(number=1000, repeat=5))
0.64559602737426758

which is even easier and faster. But even comparing a pure Python key 
function to the cmp function, it's obvious that cmp is nearly always 
slower.

Frankly, trying to argue that cmp is faster, or nearly as fast, is a 
losing proposition. In my opinion, the only strategy that has even a 
faint glimmer of hope is to find a convincing use-case where speed does 
not matter.

Or, an alternative approach would be for one of the cmp-supporters to 
take the code for Python's sort routine, and implement your own sort-with-
cmp (in C, of course, a pure Python solution will likely be unusable) and 
offer it as a download. For anyone who knows how to do C extensions, this 
shouldn't be hard: just grab the code in Python 2.7 and make it a stand-
alone function that can be imported. 

If you get lots of community interest in this, that is a good sign that 
the solution is useful and practical, and then you can push to have it 
included in the standard library or even as a built-in.

And if not, well, at least you will be able to continue using cmp in your 
own code.

I can use my psychic powers to solve the crime!

I did a test on the Australian Channel 9 News website a few months
ago...

Given a sequence of photos tell who is a notorious criminal and who is
a professional surfer!

I got every one right!  My psychic channels were spot on, e.g. "had a
big magazine following" -> SURFER

Forcing absolute package imports in 2.7?

2011-03-30 Thread Michael Parker

Hi all,

I'm reading Learning Python 4th Edition by Lutz. In the section on
relative package imports, he says: "In Python 3.0, the `import
modname` statement is always absolute, skipping the containing
package’s directory. In 2.6, this statement form still performs
relative imports today (i.e., the package’s directory is searched
first), but these will become absolute in Python 2.7, too.`

But in my own testing I'm not seeing this behavior. Was it not
included in 2.7 for fear of breaking too many programs?

Thanks!
- Mike

print "How much do you weigh?", weight = raw_input()
print "So, you're %r old, %r tall and %r heavy." % ( age, height,

Note:
Notice that we put a , (comma) at the end of each print line. This is
so that print doesn’t end the line with a newline and go to the next

1. Go online and find out what Python’s raw_input does.
$ python ex11.py How old are you?
35 How tall are you?
6'2" How much do you weigh? 180lbs
So, you're '35' old, '6\'2"' tall and '180lbs' heavy.

Related to escape sequences, try to find out why the last line has
’6\’2"’ with that \’ sequence. See how the single-quote needs to be
escaped because otherwise it would end the string?

Each language should be used for its strengths, not its weaknesses :)
If you're using Python, keep it light and simple and then just restart
the program. If you want to reload stuff without restarting, grab
Pike. There's no point fighting your language!

FBI cryptanalysis hasn’t decrypted notes from 1999 murder mystery

http://tinyurl.com/4d56zsz

The FBI is seeking the public's help in breaking the encrypted code
found in two notes discovered on the body of a murdered man in 1999.

The FBI says that officers in St. Louis, Missouri discovered the body
of 41-year-old Ricky McCormick on June 30, 1999 in a field and the
clues regarding the homicide were two encrypted notes found in the
victim's pants pockets.

The FBI says that despite extensive work by its Cryptanalysis and
Racketeering Records Unit (CRRU), and the American Cryptogram
Association, the meanings of those two coded notes remain a mystery
and McCormick's murderer has never been found. One has to wonder
though, if the FBI can't figure this out, who can? But I digress.

From the FBI: "The more than 30 lines of coded material use a
maddening variety of letters, numbers, dashes, and parentheses.
McCormick was a high school dropout, but he was able to read and write
and was said to be 'street smart.' According to members of his family,
McCormick had used such encrypted notes since he was a boy, but
apparently no one in his family knows how to decipher the codes, and
it's unknown whether anyone besides McCormick could translate his
secret language. Investigators believe the notes in McCormick's
pockets were written up to three days before his death."

"Standard routes of cryptanalysis seem to have hit brick walls," said
CRRU chief Dan Olson in a statement. To move the case forward,
examiners need another sample of McCormick's coded system-or a similar
one-that might offer context to the mystery notes or allow valuable
comparisons to be made. Or, short of new evidence, Olson said, "Maybe
someone with a fresh set of eyes might come up with a brilliant new
idea."

The FBI says it has always relied on public tips and other assistance
to solve crimes though breaking a code may represent a special
circumstance.

For larger images of the notes go here. [LINK]

If you have an idea how to break the code, have seen similar codes, or
have any information about the Ricky McCormick case, write to CRRU at
the following address:

FBI Laboratory
Cryptanalysis and Racketeering Records Unit
2501 Investigation Parkway
Quantico, VA 22135
Attn: Ricky McCormick Case

There is no reward being offered, just the knowledge that you may be
solving an intriguing murder mystery, the FBI stated.

No other information about the guy? It might help. If the note is of any
use then people and places would be in it. If that is the case then it
would help to know where he lived and some of the names of people he knows.

The note seems like it may not be just encrypted but a sort of
compression(or rather shorthand/jargon) was used. Was the guy a drug
dealer? It could be a list of "clients" or information about where he
sold drugs(the numbers look like street addresses or amounts.

If these kinda notes were so common from this guy then surely the FBI
should have many more?

Seems like the FBI could do more if they wanted it really solved...

First of all, out of respect for the deceased, Ricky McCormick and
in keeping with a spirit of fairness, I must say that what follows
may be pure coincidence, perhaps a 10% chance of mistaken identity
and a 90% chance of not-mistaken identity.

Background on a Joplin, Missouri 1982 killing/murder
the person killed: Darrell Ruestman
the killer: Alan J. Bannister

The prosecution's theory was that AJ Bannister murdered Darrell Ruestman.
This led to AJ Bannister's murder conviction, which was upheld
on appeal.

But see this if you wish for another theory:
< http://pubs.socialistreviewindex.org.uk/sr214/usletter.htm > .

In any case, Darrell Ruestman was killed in 1982.

From the case: BANNISTER v. DELO,
<
http://mo.findacase.com/research/wfrmDocViewer.aspx/xq/fac.%2FFDCT%2FWMO%2F1995%2F19950915_019.WMO.htm/qx
>

This court opinion mentions three affidavits:
1. Wooten Affidavit
2. Taylor Affidavit
3. Trombley Affidavit (writer and film maker)

In the Trombley Affidavit, one finds:
"Finally, Trombley's statement about what Bannister says happened directly
contradicts the testimony of Linda McCormick, Ruestman's girlfriend, who was in
the trailer at the time of the murder and testified that she heard no
conversations before hearing the shot. See Tr. III at 49, 65. "

and also:

"For instance, Trombley links McCormick to Wooten and Wooten to Ruestman's
murder (thereby conflicting with Wooten's affidavit). However, Trombley also
connects Wooten and Bannister. See affidavit at 9. These facts could support the
State's theory that Wooten, acting as a middleman for McCormick, hired Bannister
to murder Ruestman just as easily as they support Trombley's accidental shooting
theory."

It seems you are asking about modules and namespaces whereas you
actually want to ask about how to optimize your development
environment -- Yes?
IOW a programmer normally starts with a vague idea, moves to/through
increasing details with the implementation moving from incomplete to
buggy to finished.

Modules (and shrink wrapping in general) is good in the later stages
and a nuisance in the earlier.
As an alternative if you use emacs and python-mode then you can hack
away with C-c C-c (py-execute-buffer) without the problem you
describe.  Then module-arize when done.
