Quick alternative
import timeit
start = timeit.default_timer()
#Your statements here
stop = timeit.default_timer()
print('Time: ', stop - start)
You might want to take a look at the timeit module:
or the profile module:
There are some additionally some nice tutorials here:
And the time module also might come in handy, although I prefer the later two recommendations for benchmarking and profiling code performance:
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
@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$
