Measure time elapsed in Python?

Question

What I want is to start counting time somewhere in my code and then get the passed time, to measure the time it took to execute few function. I think I'm using the timeit module wrong, but the docs are just confusing for me. import timeit start = timeit.timeit() print "hello" end = timeit.timeit() print end - start

Answer 1

timeit() is generally used to time very small parts of code. For anything larger than just a line or two, a common, simple way to measure time in your Python code is as follows:

import time

startTime = time.perf_counter()

... some code here ...

endTime = time.per_counter()

print ("This code took %f seconds to run" % (endTime-startTime))

Granted, there may be a small effect from the startTime and endTime assignments.
