There's an optional <code>cookies=</code> that can be provided for a <code>requests.Session</code> (as well as request) objects:

cookies = None

<blockquote>
 A CookieJar containing all currently outstanding cookies set on this
 session. By default it is a RequestsCookieJar, but may be any other cookielib.CookieJar compatible object.
</blockquote>

see: <a href="https://2.python-requests.org/en/latest/api/#requests.Session.cookies" rel="nofollow noreferrer">https://2.python-requests.org/en/latest/api/#requests.Session.cookies</a>

So it becomes:

<pre><code>s = requests.Session(cookies=cj)
</code></pre>

Update: I was confusing the the <code>requests.get</code>, <code>request.post</code> etc..., as correctly pointed out by <a href="https://stackoverflow.com/users/1350899/mata">mata</a> in comments - cookies is an attribute of the session object, not a init parameter, so this won't work. s.cookies = cj after constructing the session will:

Therefore, use:

<pre><code>s = requests.Session()
s.cookies = cj
</code></pre>

s = requests.Session()
s.cookies = http.cookiejar.MozillaCookieJar(&quot;anything.txt&quot;)

for example, i will acces google site and save the cookiejar to file &quot;anything.txt&quot;
<pre><code>s.get(&quot;https://google.com&quot;)
s.cookies.save()

And in the future, i access google again with my cookiejar.

Python 3.x code, fully working and well-implemented example. The code is self-explanatory.

This code properly handles "session cookies", preserving them between runs. By default, those are not saved to disk, which means that most websites would require you to constantly login between runs. But with the technique below, all session cookies are kept too!

This is the code you are looking for.

<pre class="lang-py prettyprint-override"><code>import os
import pathlib
import requests
from http.cookiejar import MozillaCookieJar


cookiesFile = str(pathlib.Path(__file__).parent.absolute() / "cookies.txt") # Places "cookies.txt" next to the script file.
cj = MozillaCookieJar(cookiesFile)
if os.path.exists(cookiesFile): # Only attempt to load if the cookie file exists.
 cj.load(ignore_discard=True, ignore_expires=True) # Loads session cookies too (expirydate=0).

s = requests.Session()
s.headers = {
 "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36",
 "Accept-Language": "en-US,en"
}
s.cookies = cj # Tell Requests session to use the cookiejar.

# DO STUFF HERE WHICH REQUIRES THE PERSISTENT COOKIES...
s.get("https://www.somewebsite.com/")

cj.save(ignore_discard=True, ignore_expires=True) # Saves session cookies too (expirydate=0).
</code></pre>

How can I load a CookieJar to a new requests.Session object?

<pre><code>cj = cookielib.MozillaCookieJar("mycookies.txt")
s = requests.Session()
</code></pre>

This is what I create, now the session will store cookies, but I want it to have my cookies from the file (The session should load the cookieJar). 
How can this be achieved? 
I searched the documentation but I can only find code examples and they are never loading a cookieJar, just saving cookies during one session.

requests.Session() load cookies from CookieJar
