Question

Using Python on a Windows machine, write a program that compares the execution time of a function call to a system call.

Answer 1

import os
import time
import subprocess
def fun1():
    print('Write a program to compare execution time\n')
    print('Function 1\n')

def fun2():
    subprocess.call(["dir"], shell=True)

start_time = time.time()
fun1()
end_time = time.time()
print('Time taken by python function')
print(end_time-start_time)
start_time = time.time()
fun2()
end_time = time.time()
print('Time taken by system call')
print(end_time-start_time)
print('Exiting application...')
