Hello,
I've stumbled over a behavior related to default function arguments which
appears to be a bug, from what I can tell. See this snippet:
>>> from kdecore import KURL
>>> u = KURL( "http://www.example.org/test/../"; )
>>> u.cleanPath()
Traceback (most recent call last):

This is silly. How do I access data files I've installed with distutils? In a
portable, generic way, I want to find out what is the following path on most
systems:

How do I figure out the rest, if I know foo/bar.txt? sys.prefix doesn't get
Hello,
I have trouble installing a data directory which is not a child of my package
directory in the source directory.
My source directory looks like this:
./setup.py
schemas/*.xsd
foo/*.py
And when it's installed, it should look like:
site-packages/foo/*.py
site-packages/foo/schemas/*.xsd

Hello,
Have a look at this recursive function:
def walkDirectory( directory, element ):
element = element.newChild( None, "directory", None ) # automatically
appends to parent
element.setProp( "name", os.path.basename(directory))
for root, dirs, files in os.walk( directory ):
That's what PyChecker tells me, at least.
A line of:
if testReport is not None:
results in:
runner.py:587: Using is not None, may not always work
In what circumstances can `is not None` fail? How and why does it fail?
What is the equivalent expression which is more secure; `!= None`?

Hello,
Since Python doesn't have static typing, how is the same result as traditional
function overloads results in acheived? With function overloads the
"selection of code path depending on data type" is transparent and automatic
since the typing system figure out what goes to what.
But in P

I changed all base classes in my project to inherit object. There appears to
be no reason to not do it, AFAICT.
Thanks,

I find this a nice solution. The most practical would be if it was possible to
do this with print,
Nah, I don't think it's a function, but rather a builtin "statement". But it's
possible to invoke it as an function; print( "test" ) works fine.
So I wonder, what _is_ exactly the print statement? The untraditional way of
invoking it(without paranteses) makes me wonder.

Hello,
I take PyChecker partly as an recommender of good coding practice, but I
cannot make sense of some of the messages. For example:
runner.py:878: Function (main) has too many lines (201)
What does this mean? Cannot functions be large? Or is it simply an advice that
functions should be sm

Hello all,
I have a couple of questions related to module importing.
1) When I start my Python program with `python foo.py` instead of simply
adding a interpreter comment on the first line and do `./foo.py`, some
"local" imports fails, I guess because current working directory is
different. I

In my use of getopt.getopt, I would like to make a certain parameter

it's specified, but I also want to make the parameter itself
