We used to have a site called UselessPython for that but last time I 
visited it was down. I don't know if its been resurrected but it was a 
useful resource for that kind of thing.


Other sources are the simple tool scripts that come with Python.
Look in the Library folders and you will find various sample/tool 
folders that you can investigate.

You should run this from the command line to see the errors and tracebacks.
You have a `firstname` and `lastname` variable, no `name` variable.

Traceback (most recent call last):
  File "py_tutor.py", line 34, in 
STATS()
  File "py_tutor.py", line 26, in STATS
details=name+"\n"+town+"\n"+county
NameError: global name 'name' is not defined

Once you fix that with something like `name = firstname + ' ' + 
lastname` you'll get a further error


Press the enter key to exit.
Traceback (most recent call last):
  File "py_tutor.py", line 39, in 
_ = input("\n\nPress the enter key to exit. ")
  File "", line 0

Which is because input() converts the input to an integer so you would 
need to type for eg 0 then enter for it to exit without failing. 
Changing that to raw_input() like the rest of your inputs will fix that.

(I'm assuming you are on Windows) Open a DOS window and cd to the directory 
where you have stored your script. Invoke it with

python 

When you now enter the data your script is asking for you will at some point 
run into the error and get a so-called "traceback" and an error message. 
Here's how it looks on Linux (I've stored your script as tmp_adrian.py):

$ python tmp_adrian.py
hello
i am your computer
please enter your password: gorilla
Password Accepted
hello
please enter your firstname: peter
please enter your lastname: otten
what town are your from? won't
what county are you from? tell
Traceback (most recent call last):
  File "tmp_adrian.py", line 34, in 
STATS()
  File "tmp_adrian.py", line 26, in STATS
details=name+"\n"+town+"\n"+county
NameError: global name 'name' is not defined
$

Can you make sense of that message and find the bug that is causing it? Come 
back if not.

[Tutor] Mac IDE

[Robert Johansson]

Hi,

I know that there is a lot to read about different IDEs on the net but I have 
tried a couple and I'm still not pleased. My demands are not that high, when 
I'm under Windows I'm happy with IDLE (an interactive shell and debug) but the 
problem is with Mac (Python >= 2.7 and OS 10.7). IDLE had serious problems and 
TextWrangler had no interactive shell. There's a lot of other stuff to try and 
I would be grateful if someone could spare me some time on this.

Cheers, Robert

Well, if you're prepared to spend a bit of money, I've heard very good
things about Wingware, which is also available on Mac  (Note, not a user
myself currently, but has seen it before and been favourably impressed,
enough to suggest it here despite not currently actively using it myself.)
Link: http://wingware.com/

In terms of free/open source, there's also of course Eclipse with PyDev,
although I don't know how easily/well it integrates into the Mac ecosystem,
but suffice it to say Mac is listed as a supported platform.  I use Eclipse
with PyDev on Linux and Windows and am quite happy with it.  Links:

Uselesspython is down, but you can reach a lot of the stuff through

I'll second that. If you're really into IDEs, Wingware is a great one - they
also have a student/open source license that may be right up your alley.

My personal favorite?

Two terminal windows - one with Vim, editing my Python scripts, and another
with an interactive interpreter. Since you can map keys in Vim, I have 
mapped to save and run current file. If you're in the habit of editing
multiple files you could set it up to map  to ask which file you want to
set as your main .py file. And since you mentioned debug, I usually just use
pdb if I need debugging. You could easily map a key such as  to insert a
new line and type 'pdb.set_trace()'. Vim has a fairly steep learning curve,
but if you spend 30 minutes with the vimtutor you'll be fine. With newer
versions of Vim you can also write plugins for them in Python.

Of course these capabilities (and many many more) are available with Emacs.

I personally recommend that you learn one (or both) of these editors. They
will highly improve the speed at which you are able to edit your code.

HTH,
Wayne

Re: [Tutor] where to look for python codes

[Chris Fuller]

Unless you are explicitly reading a tutorial, the code you will be looking at 
isn't going to be beginner-level in general, but you can look at smaller 
snippets and libraries then work up from that.

http://effbot.org/zone/
http://code.activestate.com/recipes/langs/python/
http://pypi.python.org/pypi
http://www.doughellmann.com/projects/PyMOTW/
http://www.secnetix.de/olli/Python/

There's plenty of good links right on the Python web site for beginners:

[Tutor] a quick Q: how to use for loop to read a series of files with .doc end

[lina]

Hi,

I want to read a bunch of *.doc file in present working directory,

how can I use for to read one by one and do further work,

sorry,

what's the best reference webpage I can use?

I googled, lots of distracting info, and I barely can understand how they
think.

Thanks,


import glob

for FILE in glob.glob('*.xpm'):
print FILE

How do I not print FILE,
I want to put those files in a for loop

and then further to read one by one,

Thanks,

Look in the os module for things like this.  In particular (untested):

import os.path

for fileName in os.listdir(".")
if os.path.isfile(fileName) and os.path.splitext(fileName) == "doc":
filedata = open(fileName)
xxxdosomething with filedata

Another IDE to consider that supports the MAC OS is PyCharm from JetBrains.

The file starts from line 24 is something like

aabbccddEaabb
acbbddEbbaaca
EabcEabc
aEaaEaaa

so for the first column, I can get 1 E, second column is also 1 E, third is
0, four is 2.

namely count the occurence of E in each column.

Is your .xpm files actually text files?  Or are they binary (e.g. maybe
graphics) files?  (XPM is normally the extension of a graphics filetype.)
Treating a binary file as if its text is not liable to work very well.

Also can you please confirm whether this task is homework/study related?

I have some awk script to achieve this. I can assure you it's not homework.
LOL ... I have never attended some python course.
sometimes it's hard for you to image how hard I persuade myself to use/think
in python way, forget what is-already-relatively-easy-for-me-to-use bash
script.

the xpm file an read, I just text

f=open('1.xpm','r')
for line in f.readlines():
print line
f.close()

I am google-ing how to get the line index, so will use those after 24.

Once you've tested that, then you're ready to just look at line 24.

 I'll second that. Vim (not vi - more on that later) is my IDE. I
 have customized it using vimscript and what I have is as feature -
 rich as any out-of-the-box IDE - but with differences.

> Of course these capabilities (and many many more) are available with Emacs.

  I used Emacs extensively in the past. Vim is my preference, but
  emacs has a feature that is not present (yet) in vim : the ability
  to run interpreters - as an example the terminal shell and the
  python - asynchronously inside of the application.  This is a very
  handy feature, eliminating the second application window.

> I personally recommend that you learn one (or both) of these editors. They
> will highly improve the speed at which you are able to edit your code.
  I would not wish vim or emacs on anyone who doesn't wish to use
  them. But for someone with an open mind, some points :
  . 'vim' is not 'vi', but is 'descended from' vi.
  . There is 'vim' - teminal mode and 'gvim' - vim with gui.
I use vim as my default midnight command editor, gvim as my
'IDE'
  . Emacs can be run in terminal mode also, with greater speed, but
less features.
  . There are 'easy' modes available for both, enabling a new user to
find themselves in a more familiar environment.
  . The python interpreter can be compiled into vim. On ubuntu it is
the default. This gives the user the ability to customize vim
using python code.
  . Some call emacs and vim 'arcane'. Some ridicule vim's 'modal'
style of editing. Neither are arcane, they are very up to date
and are a parallel way of doing things.
vim modal editing is a thing of beauty. Watching a adept
vim user work can be breathtaking to observe. The corollary
would be that some consider python weird because it is
column-sensitive.

  Just sayin'

You should probably be looking in the documentation, not trying to feed it
into the interpreter.  (If you want to get help on a specific entity in
Python it's usually better to use the "help()" function, e.g:

>>> import os.path
>>> help (os.path.splitext)
Help on function splitext in module ntpath:

splitext(p)
Split the extension from a pathname.

Extension is everything from the last dot to the end, ignoring
leading dots.  Returns "(root, ext)"; ext may be empty.

>>>

Note, trying to do "help(os.path.splitext)" would not have worked before I
imported the "os.path" module.  (Differently put: Whatever you want to get
help() on, must be known to the interpreter, so must either be built in or
previously imported.)

Sorry I meant to include a link to relevant documentation:

(And apologies for forgetting to remove ther other recipients from the

default reply to address for this mailing list not default to the mailing

I found one thing a bit weird, Here is the one:

import os.path

tokens=['E']
result=[]

"""
for fileName in os.listdir("."):
if os.path.isfile(fileName) and os.path.splitext(fileName)[1]==".xpm":
"""
filedata = open("1.xpm")
text=filedata.readlines()
for line in text[23]:
print line

1] $ python try2.py | wc -l
206

now changed to:
for line in text[23:24]:
print line

2] $ python try2.py | wc -l
2

for line in text[23:25]:
print line

3] $ python try2.py | wc -l
4

the situation 1 is supposed to be 1, while it's 206, it's just tilted 90
degree of this one line, kind of split. (if I am right here).
2] is correct.
3] is supposed to be 3, right, why it's 4?

and I want to check the correctness before using
for line in text[23:len(text)-1]:
print line

I upload the 1.xpm in below link, really appreciate for the guidance.

Please go and carefully study how strings, lists etc work -- you don't seem
to grasp what "text[23]" returns vs what text[23:24] etc returns etc.  To
spell it out:  If the variable text refers to a list of strings, then
text[23] is the 24th string.  24th, because the index starts from 0.
text[23:24] by contrast, is a sublist (called a slice) that contains strings
24 and 25 from the original list.

So, if text[23] is already itself a single string, what can the following
code possibly mean?  Eg in general, what does s[0] give you if s is a
string?  A: The first character in s. So then, what does the following do:

for x in text[23]:
  print x

a: It steps through the letters in text[23] and prints each in turn (on a
new line.)

So what you then do when you "wc -l" text[23], is to effectively count the
number of characters in line 24

You should probably just have run the script without the wc -l and this
would've become very clear very quickly on inspecting the output.   ;)

The other results are similarly explainable, by examining the output. (To be
exact, the lines in the sublists/slices include newline characters.  When
you print them seperately, you therefore end up with more lines than you
think.  Try "print line.strip()" to get rid of the newline.  Try the
following in the python interpreter:

f=open('C:\\Users\\walterp\\Desktop\\1.xpm')
>>> lines=f.readlines()
>>> slice1=lines[23]
>>> slice2=lines[23:24]
>>> slice3=lines[23:25]
>>> print slice1
>>> print slice2
>>> print slice3
>>> print len(slice3)

etc.

I checked,

::
proAB_processed.pdb
::
ATOM  1  H52 CUR 1  33.502  30.958  -9.831 -0.71 -0.23
H

the output added:

::
proAB_processed.pdb
::

without truly sorting,

but I do think you understand correctly.

Thanks, I truly understand now. There was a "blank line", and the strip()
works.

(I learned C 10 years ago, but barely used. so can understand something very
basic. Thanks again for your explaination)

Now I am facing how to read each column about the occurence of some letter.

Long time ago, my senior left me a script with the following line,

for line in text:
result.append({t:line.count(t) for t in tokens})

for index,r in enumerate(result):
print(index,"-",r)

I don't understand how it works, kinda of transpose a matrix?

What format are the doc files?
If they are word processor files they may well be in binary format so 
you will need to either decode them (using struct?) or find a module 
that can read them, or a tool that can convert them to something you can 
read.


Once you figure out how to read a single file reading multiple files can 
be done in a number of ways including using os.walk() and a

for loop (or the fileinput module).

for root,dirs,files in os.walk(path):
docs = [f for f in files if f.endswith '.doc'] # or use glob
for line in fileinput.input(docs):
#process line


But the hardest bit is likely going to be the reading of the files if 
they are not plain text.

I'm the opposite, all my lists work this way.
I think the older lists tend to work like Python because all the
older list managers (eg listserv etc) tend to work thataway.
With the advent of web mail systems lists seem to be swinging
the other way, but most of my mailing lists pre-date the web
by a long way! :-)

But I haven't used the most recent OS X releases (post Tiger)
(I'm still on a G3 iBook!) so the tool selection may have changed.

Netbeans is another option that works on a Mac. There is
a plugin for Python. From memory this includes an interpreter
window.

Finally, I can also add that the native MacOS developer tools,
including XCode work with Python, but it doesn't include an
integrated interpreter. You need to install/configure XCode
to work with Python, visit the Mac Python pages for details.

Sorry this it should be:
for line in processed:

This worked for me.

>>> not the data
[['ATOM',  '2',  'H20',  'CUR',  '1',  '30.338',  '28.778',  '-6.812',  '1.00',

 ['ATOM',  '5',  'C19',  'CUR',  '1',  '31.790',  '29.357',  '-8.323',  '1.00', 
 '0.00']]
>>> pprint.pprint( sorted( processed, key= lambda x: mapping.get( x[2], 0 ) ) ) 
# I use sorted instead of processed in case it did not sort correctly (that way 
I still have the original list)
[['ATOM',  '5',  'C19',  'CUR',  '1',  '31.790',  '29.357',  '-8.323',  '1.00',

You should note, that I just used "print" I did not write to file. You will 
need to actually create/open a file, run through the list (e.g. processed) and 
write to the file, and then finally close it.

I would have preferred it to set the list as the TO and the originator as the 
reply CC. 
Not sure if that works with the email standards if it just "appears" to work 
that way from Outlook.
That way I can reply by default to the list and if I want to send to the 
originator I can
also do reply all.

Re: [Tutor] where to look for python codes

[bodsda]

I would suggest looking on http://ubuntuforums.org for the “Beginner 
programming challenges“ - there is an index of past challenges as a sticky in 
the programming talk subforum. A large number of entries for these challenges 
are in python, and as the name implies, the submissions are usually written by 
beginners.

The code will not be enterprise standard, but it should be a good insight into 
how others write python programs

Hope this helps,

Hi,

I know that there is a lot to read about different IDEs on the net but I have 
tried a couple and I'm still not pleased. My demands are not that high, when 
I'm under Windows I'm happy with IDLE (an interactive shell and debug) but the 
problem is with Mac (Python >= 2.7 and OS 10.7). IDLE had serious problems and 
TextWrangler had no interactive shell. There's a lot of other stuff to try and 
I would be grateful if someone could spare me some time on this.


Well, if you're prepared to spend a bit of money, I've heard very good things 
about Wingware, which is also available on Mac  (Note, not a user myself 
currently, but has seen it before and been favourably impressed, enough to 
suggest it here despite not currently actively using it myself.)  Link: 
http://wingware.com/

I'll second that. If you're really into IDEs, Wingware is a great one - they 
also have a student/open source license that may be right up your alley.

My personal favorite?

Two terminal windows - one with Vim, editing my Python scripts, and another 
with an interactive interpreter. Since you can map keys in Vim, I have  
mapped to save and run current file. If you're in the habit of editing multiple 
files you could set it up to map  to ask which file you want to set as your 
main .py file. And since you mentioned debug, I usually just use pdb if I need 
debugging. You could easily map a key such as  to insert a new line and 
type 'pdb.set_trace()'. Vim has a fairly steep learning curve, but if you spend 
30 minutes with the vimtutor you'll be fine. With newer versions of Vim you can 
also write plugins for them in Python.

Of course these capabilities (and many many more) are available with Emacs.

I personally recommend that you learn one (or both) of these editors. They will 
highly improve the speed at which you are able to edit your code.

HTH,
Wayne

 I just got a 2011 mac mini with the last OS ... time doesn't permit
 me to fire it up until tomorrow at the soonest, but I will report
 back on emacs and vim as defaults. A distribution call macvim is
 available and vim can also be custom built.

Well, for that particular (comparatively rare) case, with copy and paste.
(Which is in any case basically what I have to remember to do each and every
time I reply to the list-only currently, assuming I've also remembered to
click reply-all instead of reply...)

IMHO, ideally things should work exactly as they are except that "Reply"
goes to the list, "Reply-all" sends to the list as well as anyone else
(which then allows copying and pasting/re-arranging of addresses etc if only
some people are meant to get the response.) As I say, this would be
consistent with how most other mailing lists (that I'm on anyway) works.
IMHO the current default behaviour makes the most common use-case more work
than it would otherwise be, but fine, if the powers that be actually want it
like it is, then who am I to argue. :)

Yes... well I don't want to start an argument, but I can't help but point
out that just because things might've in sometimes in the past been set up
to work like that doesn't mean it's neccesarily the most appropriate way it
should be done today, in general, or on this list in particular.

But, as I say, I don't want to start an argument -- if this has been debated
before (and you've just told me it has), and so has been deliberately and
intentionally set to the current behaviour then that's fine.  I'll not say
another word about it.  :) (I'll however reserve the right to have a few
choice thoughts about it next time I again forget to swap around the
addresses on reply-all, or when I again robotically click reply instead of
reply-all when responding to this list and end up sending a reply to the
person only instead of to the list and then have to go dig the reply out the
sent box again and forward it on to the list manually...  ;) )

Best,

In fact, every e-mail client is technically capable of receiving
messages from the future! Unfortunately, there are as of this writing
no clients that can send messages into the past :(

The archives go by the date header found in the e-mail. This is
supposed to indicate the time that the e-mail was sent. So we are left
with two options:

* someone from the future is in need of python help and is sending
messages back in time.
* someone has their system clock set wrong.
