Python loop time

I am trying to loop a while loop in a while loop, the total time it takes to execute, and write down the time it takes to do this, every time it loops. I need a way to achieve this using my code, if possible, or open up various concepts that I don't know about yet.

import random
import time
import sys

def main():


    looperCPU = 500
    start = time.time()
    while (looperCPU != 0):
        #start = time.time()

        #this is the computation for 3 secs
        time.sleep(3)
        random_number = random.randint(0,1000)

        #Send to printer for processing
        #.75 secs to 4.75 secs to generate a pause before printing
        secondsPause = random.uniform(.75,4.75)


        #This is the printer function
        printerLooper = True
        while printerLooper == True :
            print("Sleeping for ", secondsPause, " seconds")
            print(random_number)
            printerLooper = False


        #
        print("total time taken this loop: ", time.time() - start)
        looperCPU -= 1    



main()

The loop will print the time, but I am very sure that it does not take into account the wait time of the nested loop. How can I let python use the time both in the loop and in each loop that it will need to do (in this case 500)?

In python, you can study this document https://docs.python.org/2/library/timeit.html
Stackoverflow example: How to use the timeit module

import timeit
timeit.timeit('"-".join(str(n) for n in range(100))', number=10000)

In a Jupyter Laptop

%%timeit -n 100
import pandas as pd
s = pd.Series([101.00, 121.00])
summary = 0
for item in s:
    summary+=item
