Timing python programs

Question

So I am trying to see how long it takes my program to run, and the solution I came up with is:

import datetime

time1 = datetime.datetime.now()

[program code]

time2 = datetime.datetime.now()

print(time2 - time1)

I want to know if this is an efficient/correct solution, because all the guides I could find on the internet would use modules such as timeit, etc.

I would appreciate any feedback.

Also please [format your code](https://meta.stackoverflow.com/questions/251361/how-do-i-format-my-code-blocks). — user202729, May 12 '18 at 02:22

Yes, that works. However, another solution is:

import time

start = time.time()

# do stuff

print(time.time() - start)

You could also use time.clock() instead of time.time()

Okay, Thanks. Is this method more precise than my solution? – DavidNiu May 12 '18 at 23:49

Both are very precise, you can use whichever one you want. – Anish Shanbhag May 12 '18 at 23:59
