simple CPython program and its performance measure

Question

how make a simple cpython program from scratch and measure it performance gain with its respective python program.. example if I make a program of 10! in python and the in Cpython how would I know how much it improves the performance of computation.

Answer 1

Take a look at : How to use timeit module

simple code to test time taken for a function:

def time_taken(func):
    from time import time
    start = time()
    func()
    end = time()
    return (end - start)

def your_func():
    #your code or logic


# To test
time_taken(your_func)

Use this mechanism to test time taken in both situations.

Let's say CPython took c seconds & Python took p seconds, CPython is faster than Python by: (c - p) * 100 / p

If c is 2 secs & p is 1 sec. CPython is faster than Python by (2-1)*100/1 = 100%

However, the performance keeps changing depending on the code & problem statement.

Share the output. Goodluck!
