How to save requests (python) cookies to a file?

There is no immediate way to do so, but it’s not hard to do.

You can get a CookieJar object from the session with session.cookies, and use pickle to store it to a file.

A full example:

import requests, pickle
session = requests.session()
# Make some calls
with open('somefile', 'wb') as f:
    pickle.dump(session.cookies, f)

Loading is then:

session = requests.session()  # or an existing session

with open('somefile', 'rb') as f:
    session.cookies.update(pickle.load(f))

The requests library uses the requests.cookies.RequestsCookieJar() subclass, which explicitly supports pickling and a dict-like API. The RequestsCookieJar.update() method can be used to update an existing session cookie jar with the cookies loaded from the pickle file.
