Question

I'm writting a code with at least 3 defined functions. At the end, I want to print the eficiency of each functinon.

def function_1 ():
...
def function_2 ():
...
def function_3 ():
...

time of execution function_1 (): 0.0054 mileseconds
time of execution function_2 ():0.0233 mileseconds
time of execution function_3 ():0.0478 mileseconds

How can I do this ?

Answer 1

Paste this in the end of each function, so you will get timestamp after function execution

import time
import datetime

ts = time.time() // <--- this
print ts // <--- this

// or

st = datetime.datetime.fromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S') // <--- this
print st // <--- this

I'm not sure how deep you want to get with performance. I found this blog to be very helpful.
