Python speed testing - Time Difference - milliseconds

Question

What is the proper way to compare 2 times in Python in order to speed test a section of code? I tried reading the API docs. I\'m not sure I understand the timedelta thing.

Answer 1

time.time() / datetime is good for quick use, but is not always 100% precise. For that reason, I like to use one of the std lib profilers (especially hotshot) to find out what's what.
