How to see the running time of a python program using terminal command

rated 0 times [ 3] [ 0] / answers: 1 / hits: 1108 / 1 Year ago, wed, december 7, 2022, 3:59:24

I want to know whether there is a terminal command that displays the execution time for a python program ? For example using time ./proram_name to display the execution time for C++ program. For example I used g++ hello.cpp -o hello && time ./hello in the terminal to build and see the execution time for the C++ program. And the result was :

Hello world!



real    0m0.009s  

user    0m0.000s  

sys     0m0.009s

I tried the same as I used in C++. But since there is no object file ie. hello.exe, created so it wasn't that much handy.

You can use bash time like this:

time python3 proram_name.py

I would suggest to do this inside python. Basic example from the python manual:

import time



start = time.time()

print("hello")

end = time.time()

print(end - start)

You can use it to time the whole program but also to time specific functions. Far more useful than from bash.
