I've done some further testing on the subject:
I also added some calculations in the main loop to see what effect
they would have on speed. Of course, I also added the same

Mailinglogger provides two handlers for the standard python

Python typically stores floats in binary, not decimal. The
value 0.04 isn't exactly representable in binary, so the
division float(1)/25 can't produce 0.04:

Hello,
The problem might be that, aside from creating the Popen object, to
get the command run you need to call 'communicate' (other options, not
used with the Popen object directly, are 'call' or 'waitpid' as
explained in the documentation). Did you do that?

"""
obj1 = RichComparisonClass()
obj2 = Ric

Importing __future__ in the statement or the setup doesn't work
since it's not the beginning of the code being compiled. Other
than using a separate module, I could only come up with this:
timeit.template = 'from __future__ i
