No, but wxWidgets is quite mature and my experience is that it's
faster than Qt (partly, I think, because it always uses the native
widgets).

I 'm currenty working on a project for which it would be great to use
a dictionary. At the begining I have a list of strings that should
represent the keys in the dictionary. When I try to create a
dictionary it rearanges the keys. For this dictionary it is realy
important to keep the right order.
See http://www.python.org/doc/faq/general/#how-are-dictionaries-implemented
. In short, keys() and items() return an arbitrary ordering. I think
that http://pypi.python.org/pypi/Ordered%20Dictionary/ will do what
you want if key ordering is a necessity.

I've switched back to pygresql. I think a lot of my problems were
caused by not having installed postgresql-server-dev-8.2 which
contains a lot of header files etc. I'm sure this was part of the
problem with the psycopg modules aswell.

any good tutorials for using C/C++ to optimize python codebase for

how widely do they use such kind of mixed coding practices?
