Find the speed limiting part of your Python code

Say you have a Python code, 'simple.py' like this:

import time
def func_A():
    time.sleep(1)
def func_B():
    time.sleep(10)
    
if __name__=='__mian__':
    func_A()
    func_B()

and you want to figure out which part takes the most time to finish. What you can do is:

python -m cProfile simple.py

However, the output is kinda too complicated to understand.
A better way is to use 'cprofilev', which you can install from here.

python -m cProfilev simple.py

Output would look like:

[cProfileV]: cProfile output available at http://127.0.0.1:4000

Just go to http://127.0.0.1:4000 and all the information are right there waiting for you.
