Using requests sessions

session_example.py

import requests

urls = ['https://en.wikipedia.org/wiki/%s' % n for n in range(100)]

# Code that creates a new connection for every request
for url in urls:
    r = requests.get(url)
    data = r.text
    print len(data)


# The same code using sessions
with requests.Session() as session:
    for url in urls:
        r = session.get(url)
        data = r.text
        print len(data)
