Hi, I have been playing with set operations lately and came across a
kind of surprising result given that it is not mentioned in the
standard Python tutorial:
with python sets, intersections and unions are supposed to be done
like this:
In [7]:set('casa') & set('porca')
Out[7]:set(['a', 'c'])
I use VIM here too. Mainly because i always switch from Windows to Linux and
using the same text editor is a way to avoid getting crazy.

Hi,
Nowadays the addition of functionality to programs by means of
plugins is very frequent.
I want to know the opinions of experienced Python developers about the
best practices when it comes to developing a plugin system for a
Python package.
Should plugins be modules in a separate package?

Compiling f2py extensions in Linux is a trivial task, You can even

Iterating over the items and checking if it is selected, sounds like a
good idea, but there no obvious way to get a hold of the list of

Any PyQt guru lurking around?
should I try some other list widget, that has a "getSelected()"method?
Is there one?

I think that

is less cryptic than f.__get__(instance, class)

Its in the docs of python 2.4. I dont know about older versions:
Help on module new:
NAME
new - Create new objects of various types. Deprecated.
FILE
/usr/lib/python2.
Addendum to my last reply:
although the New Method is deprecated,
new.instancemethod (from Antoon's message) can be replaced by
from types import MethodType
f.show = MethodType(show,f)
and every thing still works.

This "new" module sounds pretty cool, too bad its deprecated...
I would not want to add a dependancy to a deprecated module in my code.
But maybe I'll check the code for instancemethod within it and see what
it does.

I have a program that uses pythondialog for its UI.
Pythondialog is a wrapper of the shell dialog and xdialog libs.
But I would like for it to switch between using Dialog ( when X is not
available ) and xdialog (when X is available)
So my question is: how can I check for the availability of X?
