How long does my Python application take to run?


python timer

The simplest way to do it is to put:

import timestart_time = time.time()

at the start and

print "My program took", time.time() - start_time, "to run"

at the end.

To get the best result on different platforms:

from timeit import default_timer as timer# START MY TIMERstart = timer()code for applicationmore codemore codeetc# STOP MY TIMERelapsed_time = timer() - start # in seconds

timer() is a time.perf_counter() in Python 3.3 and time.clock()/time.time() in older versions on Windows/other platforms correspondingly.

If you're running Mac OS X or Linux, just use the time utility:

$ time python script.pyreal    0m0.043suser    0m0.027ssys     0m0.013s

If not, use the time module:

import timestart_time = time.time()# ...print time.time() - start_time, 's'
