Re: measuring a function time

Someone should port Perl's Benchmark.pm module to python that's such a useful module to measure a functions execution time and CPU usage.

I just use ipython's functions (that are themselves just calls to the time module functions) for timing my functions...

Enter:
%timeit?
or
%time

At the Ipython command prompt to get started.

Take a look at time.clock()

I don't know if that's what he wants. The clock() method returns
processor time, not wall time.
