Hi!
I have a socket from which I would like to parse some data, how would I do
that? Of course, I can manually read data from the socket until unpack()

Any better suggestions?

Greetings!
I'm currently using Python to implement a set of tests for code that is
otherwise written in C. This code was wrapped using Boost.Python and is
then loaded into Python as module.
What I often have in C is this:

We have a few tests for some module here. These tests are under development

Hi!
I'm still mostly learning Python and there is one thing that puzzles me
about string formatting. Typical string formatting has these syntaxes:
"%s is %s" % ("GNU", "not Unix")

What I'm surprised is that this isn't supported:
