Measure running time a routine in Python

I think this helps us a lot for estimation of how long a program runs in Python. When dealing with a huge amount of data, it takes long time. Showing the running time, started time and end time are useful for logging and improving your program. Certainly there are a few of way to do that. In my view, the following bunch of code is pretty simple and understandable.

import time
from time import gmtime, strftime

# *nix system
start_time = time.time()
# Windows system
#start_time = time.clock()
print("Started the job on %s" % strftime("%a, %d %b %Y %X +0000", gmtime()))

# run all your routines since here
main()
test_1()
finish()
# To demonstrate this script, I try to print 100000 integer numbers
for i in range(100000):
    print(i)
print("It took %s seconds" % str(time.time() - start_time))
print("Finished the job on %s" % strftime("%a, %d %b %Y %X +0000", gmtime()))
