Thanks for your responses. I have read the Descriptor protocol how-to,
which clarifies method access on o
Hello,
I was wondering a bit about the differences between methods and
functions. I have the following:
def wrap(arg):
print type(arg)
return arg
class C:
def f():
pass
@wrap
def g():
pass
def h():
pass
print type(C.f)
print type(h)
Which gives the fol

Why so hard? Reversing it that way creates a copy, so you might as
well do:

gc.collect states it cannot find any unreachable objects. Meanwhile
the number of objects the garbage collector has to keep track o
Hello,
I have programmed some python script that loads a graph (the
mathemical one with vertices and edges) into memory, does some
transformations on it, and then tries to find shortest paths in this
graph, typically several tens of thousands. This works fine.
Then I made a test for this, so I co

Hello,
When using the textwrap module, the wrap will always use len() to
determine the length of the string being wrapped. This might be a
sensible thing to do in many circumstances, but I think there are
circumstances where this does not lead to the desired result.
I assume many applications of

Hello,
Recently I was looking for a Priority Queue module, and I've found
Pqueue by Andrew Snare [1]. When I use it with Python 2.4 everything
works okay, at least on the two system I've tested it on (Debian based
AMD 64) and OS PPC.
However, when I use it with Python 2.5 - again on the same mach

Hello,
I'm having some problems with pyparsing, I could not find how to tell
it to view certain words as keywords, i.e. not as a possible variable
name (in an elegant way),
for example, I have this little grammar:
terminator = Literal(";")
expr = Word(alphas)
body = Forward();
ifstat = "if" + bod
14 matches
