Measuring the time it takes for a function to run and complete in Python

Question

In Python 3.4.1, I\'m trying to measure how long it takes for a function to run and complete then recording it. I\'m currently doing it this like so:

startti         


        

Answer 1

For quick performance analyses I use the following two lines (plus imports):

import time
import numpy as np

t = time.time()
# ...
print np.round_(time.time() - t, 3), 'sec elapsed'

It's short, simple and all I usually need.

(In most cases I've imported numpy anyway. So thats no overhead for me.)
