print() not working in Python shell?

Question

When I run this code I got from here, nothing happens:

import requests
import bs4

res = requests.get('https://en.wikipedia.org/wiki/Machine_learning')

soup = bs4.BeautifulSoup(res.text, 'lxml')

foo = soup.select('.mw-headline')

for i in soup.select('.mw-header'):
    print(i.text)

Everything were installed (lxml, requests, bs4)

I cannot continue his tutorial If I'm stuck here.

Because soup.select('.mw-header') return [], this is empty array. .mw-header cannot be found in source website!

I recommend you use jupyter notebook, there will be visual results if you use it.
