How do you calculate program run time in python?

This question is related to python time runtime

The answer is


Quick alternative

import timeit

start = timeit.default_timer()

#Your statements here

stop = timeit.default_timer()

print('Time: ', stop - start)  

@JoshAdel covered a lot of it, but if you just want to time the execution of an entire script, you can run it under time on a unix-like system.

kotai:~ chmullig$ cat sleep.py 
import time

print "presleep"
time.sleep(10)
print "post sleep"
kotai:~ chmullig$ python sleep.py 
presleep
post sleep
kotai:~ chmullig$ time python sleep.py 
presleep
post sleep

real    0m10.035s
user    0m0.017s
sys 0m0.016s
kotai:~ chmullig$ 


I don't know if this is a faster alternative, but I have another solution -

from datetime import datetime
start=datetime.now()

#Statements

print datetime.now()-start
