3-legged OAuth: question about sample code in the doc

[pippipincs]

Question

The OAuth1UserHandler class only has 2 methods according to the doc. The doc don't said clearly about how many attributes the class has and what they are. So I am confused about oauth1_user_handler.request_token["oauth_token"]. What does exactly it mean? And what is the oauth_token? how to access it?

And despite I know that the verifier will come as parameter in the callback url, I still have no idea how to access verifier in my code. Will it be proccessed by a certain backend software so I can use the parameter "verifier" directly or I should access it by the OAuth1UserHandler class?

Thank you for you answering in advance!

Relevant Code

import tweepy

oauth1_user_handler = tweepy.OAuth1UserHandler(
    "API / Consumer Key here", "API / Consumer Secret here",
    callback="Callback / Redirect URI / URL here"
)
print(oauth1_user_handler.get_authorization_url())
print(oauth1_user_handler.get_authorization_url(signin_with_twitter=True))

request_token = oauth1_user_handler.request_token["oauth_token"]
request_secret = oauth1_user_handler.request_token["oauth_token_secret"]

new_oauth1_user_handler = tweepy.OAuth1UserHandler(
    "API / Consumer Key here", "API / Consumer Secret here",
    callback="Callback / Redirect URI / URL here"
)
new_oauth1_user_handler.request_token = {
    "oauth_token": "Request Token (oauth_token) here",
    "oauth_token_secret": request_secret
}
access_token, access_token_secret = (
    new_oauth1_user_handler.get_access_token(
        "Verifier (oauth_verifier) here"
    )
)
