Hi,
Rigth now I'm using two IDEs for Python, KDevelop and Eric. Both have
drawbacks. KDevelop is a multilanguage IDE, and doesn't really have
anything special for Python. There's no Python debugger, no PyDOC
integration, it's class browser doesn't display attributes. On the
other side there's Eric,

Hi,
I´ve got a problem creating persistent cache, that would be shared
between modules. There a supermodule, which calls submodules. I´d like
submodules to use cache created in the supermodule. The only way I see
right now, is to pass it as function argument, but that would require a
change in API,

Hello,
I´ve got this problem with pickle, it seems it doesn´t handle
correctly infinite values (nor does Python return overflow/underflow
error). What could I do about it? Example code:
>>> x = 1e310 #actually it would be a result of calculations
>>> type(x)
>>> x
1.#INF
>>> import pickle
>>> pic
To make things more interesting -- Solaris version:
>>> x = 1e310
>>> x
Infinity
>>> import pickle
>>> pickle.dumps(x)
'FInfinity\n.'
>>> pickle.loads(_)
Infinity
>>> pickle.dumps(x,1)
[...]

Hi,

I´m looking for some benchmarks comparing SWIG generated modules with

It´s quiet simple. x == 8*(x/8) + x%8, so x == 7*(x/8) + (x/8 + x%8)

I'm trying to migrate some R&D I've done with PHP and RAP[1] to
Python. But I've got hard time finding Python RDF/SPARQL server.
Most things I find are SPARQL clients.
Do you know of a Python library, that could do the job?
