developing a Python program that would read in a plain text message and producing the ciphertext, as well as the decipherment process. code example

Example: python code to calculate encryption time

import timeit

setup_code = "from math import factorial"

statement = """
    for i in range(10):
        factorial(i)
"""

print(f"Execution time is: {timeit.timeit(setup = setup_code, stmt = statement, number = 10000000)}")
