simply change the binding of widget to function.
Then change it back to re-enable it.

You don't say which GUI framework you are using so we can't give sample 
code but most GUIs offer a way to dynamically modify event bindings.

Here is the function (which loads when Nuke loads):
###
def theAutoplaceSnap():
 try:
 nuke.thisNode().autoplace()
 n = nuke.allNodes();
 for i in n:
   nuke.autoplaceSnap(i)
 except:
 pass

nuke.addOnUserCreate(theAutoplaceSnap)
###

I have many functions which get loaded, but this particular one needs to be
disabled when I am viewing another compositors script in the gui.

I have a python script editor in Nuke in which I can run code if need be to
run code on the fly.

Help


Presumably that function is defined in a different module than the one 
you're going to "disable" it from.  So, what you're attempting is 
commonly called "monkeypatching."


Let's say the module is   snapper  (in a file snapper.py).

All you probably need is to substitute another do-nothing function in 
its place.


import snapper

def donothing():
return

snapper.theAutoplaceSnap = donothing

If it will need to be restored later, you can copy it to a variable in 
your own module, and then copy it back later.

http://docs.thefoundry.co.uk/nuke/63/pythondevguide/callbacks.html#onusercreate

suggests that you can remove the callback with

nuke.removeOnUserCreate(theAutoplaceSnap)

You can later add it back with

nuke.addOnUserCreate(theAutoplaceSnap)

like in the code snippet you provided. If the add/removeOnUserCreate() calls 
occur in another module than the one theAutplaceSnap() is defined in you 
need to import that first and use qualified names (e. g. 
some_module.theAutoplaceSnap).

[Tutor] Is it bad practise to write __all__ like that

[Karim]

Hello,

__all__ = 'api db input output tcl'.split()

or

__all__ = """

   db
   input
   output
   tcl
   """.split()

for lazy boy ;o). It is readable as well.
What do you think?

[Tutor] KeyError?

[Shwinn Ricci]

I have an excel file that I am reading cell values from and putting them
into a dictionary. the dictionary looks like this:

scafPositions = {position[j]: direction[j]}

where position[j] is exclusively floating/numerical values and direction[j]
is exclusively strings.

When I try to find whether a test value val is in the array of positions,
and then try to look its direction up with ScafPositions[val], I get a
KeyError. Is this because my data isn't standalone numbers, but numbers that
are calculated based off other cells? Or can I not test for val?

Did you try printing the contents of scafPositions to see what it contains,
first?

Also, a traceback is helpful.

As far as introspection, which module are you using to read the excel files?
There's at least two that I know of.

http://wiki.python.org/moin/KeyError

I quote:
"Python raises a *KeyError* whenever a dict() object is requested (using the
format a = adict[key]) and the key is not in the dictionary. If you don't
want to have an exception but would rather a default value used instead, you
can use the get() method: "

Your problem is probably that you are reassigning a new dictionary to the name 
scafPositions each time instead of updating it. You should have something like 
the following.

scafPositions = {}

#loop structure here:
#do stuff
scafPositions[ position[j] ] = direction[j]

Or it could be it's not introspecting the formula within excel and his key
is the string "=A1*sheet2!$B$1"or it could be he's looking for a float / int
when in reality it's a string (because it must be converted explicitly).

Without a traceback and the code, it's hard to know for sure.

My guess is leading towards introspection.

As far as printing the contents, once you create your dict with all the data
just use the print statement / function depending on your version of python

print scafPositions or print(scafPositions)

You could loop through it as well

for key, value in scafPositions.items():
print key, value

This will give you an idea of what is in the dict.

[Tutor] Sum files' size

[Susana Iraiis Delgado Rodriguez]

I want to get the size of  3 files. I already completed this step. Then I
need to sum the 3 results I got. In order to do it I have the next code:

import os
file_list = []
folders = None
for root, folders, files in os.walk('C:\\'):
file_list.extend(os.path.join(root,fi) for fi in files if
(fi.endswith.shp))
for row, filepath in enumerate(file_list, start=1):
n = os.path.splitext(filepath)
p = n[0]+'.prj'
shx = n[0]+'.shx'
s = os.path.getsize(filepath)

#Function to get size in humam readable terms:
def sizeof_fmt(num):
 for x in ['bytes','KB','MB','GB','TB']:
  if num < 1024.0:
   return "%3.1f%s" % (num, x)
  num /= 1024.0

kb = sizeof_fmt(s)
shx1 = os.path.getsize(shx)
kb2 = sizeof_fmt(shx1)

#Finally I want to sum the 3 terms:
total = kb+kb2+kb3
But the output I got is : 15.5KB108.0bytes169.0bytes

Does anyone have an idea how to fix it?

So kb1 will be astring


shx1 = os.path.getsize(shx)
kb2 = sizeof_fmt(shx1)


And so will kb2


#Finally I want to sum the 3 terms:
total = kb+kb2+kb3


Where does kb3 come from?


But the output I got is : 15.5KB108.0bytes169.0bytes

Looks like you are adding the strings. You need to get the
sum then call your format function on the total.

Re: [Tutor] Getting Idle to work in Win7

I decided to re-install.  It looks like I'm in the same boat as

I tried from the command line to run pythonw.exe, and that gave me
the typical >>> input choice. Python at least works at that
level. IDLE comes up with idle.pyw.

There must be something wrong with your Python

try to run your Python script from the command line, as well
as starting Idle from the command line so you can see what
error message might be printed.

Open

cmd.exe and then navigate to the directory where Python is
installed (C:\Python27) for me and then cd into the
Lib\idlelib directory and run idle.bat. Hopefully there
should be some errors that show in the window. If not you
can try running it “..\..\pythonw.exe idle.pyw” and
hopefully that will show the problem.

Instead only retrieve the formatted output at the end. That way you will not

kb = s

Sum the three terms while they are still numbers, before you convert

Sending this whole thing to the entire list. You should send replies to the
list as well.

going to go bit by bit here:


def LookUp(helix, scafPos):
> book = xlrd.open_workbook('CoordinatesSpreadsheet.xls')
> sheet = book.sheet_by_index(0)


ok good so far (but don't capitalize functions)

cols = sheet.row_values(2,1,150)


Here you are getting a slice of columns, from a single row. About 149
columns worth.

position = {}
> direction = {}


You don't need these dictionaries for anything useful as far as I can tell,
so drop them

for i in range(len(cols)):
> rows = sheet.col_values(i+2, 5, 500)


This doesn't make sense with the above, you are now taking a slice of rows
from a single column. I would probably rewrite this (i'll give you a
suggestion in a moment)

for j in range(len(rows)):
> position[j] = float(sheet.cell(j+5, i+3).value)
> direction[j] = sheet.cell(j+5, i+1).value
> scafPositions[position[j]] = direction[j]
> i += 5



Ok, so position isn't a dict anymore. Just make position a straight var

Re: [Tutor] Don't understand this class/constructor call syntax

[dave]

Yes that is roughly what I meant.  GNU Radio uses a lot of sub-classing--if
this is the correct term.  For example all blocks inherit hier_block2 which
has methods such as connect for connecting two blocks together.  I wondered if
the instance named self wasn't being passed as a replacement for the implicit
self parameter rather than in place of the pass_as_USRP=True parameter.

Steven D'Aprano also replied on this subject and if I understand him, then it
would require a special syntax that is not present in the GNU Radio code.

[Tutor] Sorting lists both ways at once and programmatically loading a variable.

[Prasad, Ramit]

I have 2 questions.

1. Is there a way to do a reverse and a normal sort at the same time?
I have a list of tuples (there are more than 2 elements in the tuples but I 
only want to sort by the first two). I want to sort in reverse for the first 
element (int) and in order for the second element (string).

Example: [ (1,3) (5, 2), (5, 1), (1, 1) ]. 
The output should be:[ (5,1), (5,2), (1,1), (1,3) ]
I can create a hack for this by sorting both values in order but it is a hack 
and not a "Good" solution (untested): 
>>> sorted( lst, key=lambda x: (99-x[0],x[1]) )



2. How would you programmatically get a variable when there is no class 
involved? If I was in a class I could do something like 
>>> programmatically_determined_variable = getattr( self, var_basename + 
>>> str(number) )
How would I do this from a module function or directly in the module? And is 
the solution "safe"?

First point.  Nothing wrong with your solution, but you can leave out 
the 99 part.  Just use -x[0]
Another option.  Do two sorts, first on the secondary key, then on the 
primary (reversed).  Since Python's sort is stable,

it'll do the right thing.

Ramit

globals() is a dictionary of all the global variables, so you can do the 
same getaddr() technique.

Don't run pythonw to catch bugs, use python (no w).

Python script from the command line, as well as starting Idle from the command

Its late and I'm going to bed so this might be ruibbish, but couldn't

[Tutor] Mainloop conflict

Dear Tutor Dudes,
I have a socket Gui program. The only problem is that socket.recv waits
for a response, which totally screws Tkinter I think. I tried making the
timeout extremely small (it was alright if I didn't receive anything, I
was excepting that a lot) but I think that screwed socket. Anyone have words
of wisdom.

[Tutor] Running files from command prompt

[Alexander Quest]

I downloaded the google's python exercise files from their website (
http://code.google.com/edu/languages/google-python-class/set-up.html),
unzipped them, and placed them in C.
I then added the following to the PATH variable under system settings so
that I could type "python" in command prompt and have Windows start the
interpreter: C:\Python31;C:\Python31\Tools\Scripts

When I type in "python" in the command prompt, the interpreter opens, but
when I try to open one of the programs from the Google exercise files
(hello.py), I get the following error:
Traceback :
   File "", line 1, in 
NameError: name 'hello' is not defined

Or, if I just type in "python hello.py" first in the command prompt (as
opposed to typing in python, hitting enter, and THEN typing in hello.py, as
above), I get the following error:


python: can't open file 'hello.py': [Errno 2] No such file or directory.

So I guess my question is how do I run .py files from the command prompt now
that I seem to have gotten Windows to recognize and open the interpreter
when I type in "python"? Thanks for any help.

-Alex

P.S. Just as an aside, when I open up the command prompt, the initial
directory is C:\Users\Alexander, but my google exercises are in
C:\google-python-exercises and python itself is in C:\Python31. I don't know
if this makes a difference or not.

When you're running the python interpreter, you can't just type the name 
of your script.  You need to import it

 import hello

However, first it needs to be in the python's module search path.  
Easiest way is to make

 it your current directory.

So, from a command prompt:

cd C:\google-python-exercises

python
 starting Python version 

import hello



Or, if I just type in "python hello.py" first in the command prompt (as
opposed to typing in python, hitting enter, and THEN typing in hello.py, as
above), I get the following error:


python: can't open file 'hello.py': [Errno 2] No such file or directory.

So I guess my question is how do I run .py files from the command prompt now
that I seem to have gotten Windows to recognize and open the interpreter
when I type in "python"? Thanks for any help.

Similarly, before running python, change to the directory you want the 
script to run in.

Normally, you'd do:

cd c:\google-python-exercises
python hello.py



-Alex

Awesome- thanks for that Dave! The programs all work now, except that the
google exercise programs are all from Python 2.X and I'm running 3.1, so
some of them are giving me errors. Is there a way around this or do I have
to download a 2.X version so I can run these without a problem? Thanks

Re: [Tutor] Running files from command prompt

[Alexander Quest]

To clarify, the particular file that was giving me trouble was the basic
"hello world" file. The original code on line 29 read as such: print
'Hello', name
When I ran "C:\google-python-exercises> python hello.py, it gave me an error
on that line (line 29), but when I changed that line to print ('Hello',
name), that is, including the parentheses, it printed out "hello world" as
it should. I'm assuming that this means that one of the differences between
Python 2.X and Python 3.X is that the print function necessitates
parentheses in the latter versions but not in the former. I am a bit
confused as to why this is, assuming I am correct in my assumption above,
because I was under the impression that code written for earlier python
versions will work for later python versions, as is the case here. Anyways,
I just wanted to add this info to clarify my last question regarding whether
or not I should install Python 2.X and uninstall Python 3.1 that I have now,
since I'm guessing that doing the google exercises will continue to give me
these errors with other programs (but this is, of course, still assuming
that the error cited above truly is caused by version incompatibility).

[Tutor] About the Mailing List

[Jordan]

How do I see what in the mailing list has already been responded too,
before it sends me the digest? For instance I wanted to respond to one
of the questions, but seeing that the time was almost two hours ago. I
am sure someone has already responded. Where could I check to see if
this is true? I assume the mailing list are posted some wheres on-line.
But I can only find the sign up page. Thanks in advance for the link.

Re: [Tutor] Mainloop conflict

 I have a socket Gui program. The only problem is that socket.recv waits
for a response, which totally screws Tkinter I think. I tried making the
timeout extremely small (it was alright if I didn't receive anything, I
was excepting that a lot) but I think that screwed socket. Anyone have words
of wisdom.


Most of the GUI main loops (including tk, I believe) have a way to hook in 
additional file descriptors and sockets that can be listened on, so that 
you get a normal event when data becomes available in them.

Re: [Tutor] Running files from command prompt

To clarify, the particular file that was giving me trouble was the basic
"hello world" file. The original code on line 29 read as such: print
'Hello', name
When I ran "C:\google-python-exercises> python hello.py, it gave me an error
on that line (line 29), but when I changed that line to print ('Hello',
name), that is, including the parentheses, it printed out "hello world" as
it should. I'm assuming that this means that one of the differences between
Python 2.X and Python 3.X is that the print function necessitates
parentheses in the latter versions but not in the former. 



Yes, that is correct.

To be a programmer (whether professional or amateur), you need to learn 
to *pay attention to the error given*. "It gave me an error" is 
meaningless. What does the error message say?


In this case, I expect it is a SyntaxError. But you need to learn to 
read the error message and understand what it is trying to tell you. 
Some errors are cryptic and don't help, but generally speaking Python is 
pretty good about giving useful error messages:



>>> a = [1, 2, 3]
>>> len a
  File "", line 1
len a
^
SyntaxError: invalid syntax


Admittedly you do need to learn that Python functions require 
parentheses, but apart from that, the error tells you what is wrong: you 
can't follow a function len with another name a without something 
between them. This is illegal syntax.





I am a bit
confused as to why this is, assuming I am correct in my assumption above,
because I was under the impression that code written for earlier python
versions will work for later python versions, as is the case here. 


Not quite. It is (mostly) true for Python 1.x and 2.x, but Python 3 has 
deliberately included some backwards incompatible changes. The biggest 
two are that strings are now Unicode rather than byte strings, and that 
print is now a function instead of a statement. So, yes, in Python 3 you 
have to call it with parentheses.


The differences are still quite minor -- think of Python 2.x and Python 
3.x being like the differences between American English and British 
English. Provided you pay attention to the error messages, and remember 
to add round brackets after print, tutorials for 2.x should still 
*mostly* work.




I just wanted to add this info to clarify my last question regarding whether
or not I should install Python 2.X and uninstall Python 3.1 that I have now,


Personally, I would consider it wiser to find a Python 3 tutorial. 
Python 3 is the future, and you will need to learn it eventually.

Digest mode is a pain in the backside for people wanting to reply, and 
an even bigger pain for those who read the replies to digests. Please 
consider doing yourself, and everyone else, a favour by switching to 
individual emails.


You can see the archives by going to this page here:

http://mail.python.org/mailman/listinfo/tutor

and following the links to the archives. There are *three* given: two 
external archives (Activestate and Gmane) and one held by python.org itself.

I'll add on to that and say find the threading feature of your user
agent -- or switch to one that has said feature. I know recent thunderbird's
do it, if that's the sort of thing you're into. Thread view makes
things bucketloads easier.
