On Python 2.5 I need to use float numbers with a modified __str__() method. Also I need to know when the constructor fails. Why I can't catch exceptions raised from float.__init__()?

I have written some C++ code that generates a std::vector. I also have a python script that manipulates some data that, for now, I am declaring like this (below). import numpy x = numpy.random.randn(1000) y = numpy.random.randn(1000) I can run the script fine. From my C++ code: using namespace boost::python; try{ ...
I'd like to get busy with a winter programming project and am contemplating writing an online word game (with a server load of up to, say, 500 users simultaneously).

At the moment I have sList = [line for line in theString.split(os.linesep)] for line in SL...
Silly question, but is there a built-in method for converting a date to a datetime in Python, ie. getting the datetime for the midnight of the date? The opposite conversion is easy - datetime has a .date() method. Do I really have to manually call datetime(d.year, d.month, d.day) ? Edit: and the winner is: datetime.combine(d, time()) ...

Is there a way to measure time with high-precision in Python --- more precise than one second? I doubt that there is a cross-platform way of doing that; I'm interesting in high precision time on Unix, particularly Solaris running on a Sun SPARC machine. timeit seems to be capable of high-precision time measurement, but rather than meas...
