How to acess tweets with bearer token using tweepy, in python?

Question

When I signed up for the Twitter API for research , they gave me 3 keys: API Key, API Secret Key, and Bearer Token. However the Hello Tweepy example, 4 keys are used: consumer_key, consumer_secret, access_token, access_token_secret. Obviously, the first two keys map to each other, but I don't see how consumer_secret and access_token map to Bearer Token. I am using this:

CONSUMER_KEY = 'a'
CONSUMER_SECRET = 'b'
ACCESS_TOKEN = 'c'
ACCESS_TOKEN_SECRET = 'd'
BEARER_TOKEN='e'


# Set Connection
auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
api = tweepy.API(auth, wait_on_rate_limit=True)

Where should I use the Bearer token? Thanks

I believe the confusion lies in the different terminologies for the variables and the use of these variables.

Terminologies

First explained below, terminology clarification, with different terms referring to the same thing:

Client credentials:

1. App Key === API Key === Consumer API Key === Consumer Key === Customer Key === oauth_consumer_key
2. App Key Secret === API Secret Key === Consumer Secret === Consumer Key === Customer Key === oauth_consumer_secret
3. Callback URL === oauth_callback
 

Temporary credentials:

1. Request Token === oauth_token
2. Request Token Secret === oauth_token_secret
3. oauth_verifier
 

Token credentials:

1. Access token === Token === resulting oauth_token
2. Access token secret === Token Secret === resulting oauth_token_secret

Next, the use of these. Note that bearer Token authenticates requests on behalf of your developer App. As this method is specific to the App, it does not involve any users. Thus you can either go with requests on a user level or at an app level as follows:

User level (OAuth 1.0a):

API key:"hgrthgy2374RTYFTY"
API key secret:"hGDR2Gyr6534tjkht"
Access token:"HYTHTYH65TYhtfhfgkt34"
Access token secret: "ged5654tHFG"

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(key, secret)
api = tweepy.API(auth)  

App level (OAuth 2.0):

Bearer token: "ABDsdfj56nhiugd5tkggred"
auth = tweepy.Client("Bearer Token here")
api = tweepy.API(auth)

Or alternatively:

auth = tweepy.AppAuthHandler(consumer_key, consumer_secret)
api = tweepy.API(auth)
