line profiler in command line

The source code with @profile directive before the function we want to profile:

import requests

@profile
def slow_func():
    s = requests.session()
    html=s.get("https://en.wikipedia.org/").text
    sum([pow(ord(x),3.1) for x in list(html)])
        
for i in range(50):
    slow_func()

Using kernprof command to calculate profiling line by line

$ kernprof -lv so6.py

Wrote profile results to so6.py.lprof
Timer unit: 4.27654e-07 s

Total time: 22.6427 s
File: so6.py
Function: slow_func at line 4

Page request is almost always slower than any calculation based on the information on the page.
