Hello,
In my script library, one directory is named rendering. When I try
to import a module from this directory, I always get this error:
#ImportError: dynamic module does not define init function (initrendering)
However, there is an __init__.py file in there, and also the pyc
version. All
That would be the compileall utility:

Cheers

Hello,
Possibly I am missing something, but how do you use the repr() function?
I type this ultra-simple function:
def myFunc(): print 'hello'
Then run
repr( myFunc )
Wich returns
'function myFunc at 0x009C6630'
Okay then I run
s = repr( myFunc() )
print s
Wich returns
'None'
Thanks
Ok thanks a lot.
The real question is, then, is there a way I can print the code of a
function as a string? Something like
'def myFunction: print hello'
Thanks

Well, to make a long story short, this is because I use Python through
another software, Softimage|XSI, and by design a string is required to
pass logic to on-the-fly GUIs. Since XSI implements 3 other languages
(ActivePerl, VBScript and JScript), I suppose this was designed that way

Indeed, dictionaries don't have a .key attribute.
Instead, use:
# Get list of values for 'key1'
aList = dol[ 'key1' ]
This would return the list of values you have assigned to 'key1' in
the dictionary. Once you got that list, you can look in the list to
find out the index of 'lil1' and return
Well, that was a nice explanation. Thanks once again Kent!

Hi Joseph,
To answer your last question first, you should use the
os.path.exsits() method to see if the path is valid:
http://www.python.org/doc/2.4.1/lib/module-os.path.html
As for finding a word in a text, I would suggest to write a basic text
parser that would work on small files.
def
( raw_input( 'what word to searh:' ) )
# Call function
parseText()
# Check if list has at least one element
if len( aWords ) 1: print 'Word not found in file'
else: print str( len( aWords ) ) + ' instances of our word found in file'
Sorry again

Hi William,
First, check out the os and os.path modules. It has exactly what you
need to handle files and directories.
http://www.python.org/doc/2.4.1/lib/module-os.html
More specifically:
http://www.python.org/doc/2.4.1/lib/os-file-dir.html

Thanks Alan, that clears things up quite well.

The authors even go as far as saysing, on page 228 (first paragraph)
that map() used that way has a performance benefit and is faster than
a for loop.

I just started using list comprehensions (loving them!)
I know you can add an if statement, but can you put in there an else?
I could not find an example of this.

I have an object, and this object has attributes. These attributes are
objects in their own right, and each attribute also have its own attributes.
So I loop over the top object, and for each attribute encountered, I

Hi,
The one thing I would try, if I understand what you're after
correctly, would be to run a exec command with the module name.
modulename = 'myModule'
exec 'import ' + modulename
Then you can access the module names as any imported module.

The os module is the answer. Use chdir() to make the target executable's

the actual command.
