The lxml library creates its own request and does not store the session?

Question

Python

When requesting a site via Session(), I store cookies. Then, using lxml, I parse the received page text for the token specified in the request form.
So in this way I collect all the data for a subsequent request.
But as it turned out, when parsing the page through lxml, it gives me a new token.
It turns out that lxml creates its own request and it does not pay attention to the session declared above?

No matter how much I searched for information on sessions of the lxml library, I could not find anything.

Answer 1

I just wrote an answer:

there are no sessions, they don’t exist, this is an abstraction : at the physical level there are POST / GET requests and cookies
for their development came up with POSTMAN (well, other insomnia) , practice
yes, there are "sessions" in requests and bs, for convenience, syntactic sugar, magic - no need to rely on this

Answer 2

I mixed everything together, lxml does not create any http request at all, and does not store the session, lxml is just an html parser. Requests and session is to requests
