Three Legged Auth To Tweet Something

CONSUMER_KEY = os.getenv("CONSUMER_KEY")
CONSUMER_SECRET = os.getenv("CONSUMER_SECRET")
ACCESS_TOKEN = os.getenv("ACCESS_TOKEN")

# Create an OAuthHandler instance
auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)

if ACCESS_TOKEN and ACCESS_TOKEN_SECRET:
    auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
else:
    # Redirect user to Twitter to authorize
    redirect_user_url = auth.get_authorization_url()
    print(f"Please authorize the app at this url: {redirect_user_url}")

    # After the user authorizes, they will be redirected
    # back to your app with a verifier in the URL query string
    verifier = input('Please input the verifier: ')

    # You can now use that verifier to obtain an access token
    auth.get_access_token(verifier)

    # At this point, auth.access_token and auth.access_token_secret
    # can be saved for future use (so that you don't need to go through
    # the 3-legged OAuth process every time the user runs your app)
    ACCESS_TOKEN = auth.access_token
    ACCESS_TOKEN_SECRET = auth.access_token_secret
    # Save these in your environment or some other secure place

# Now you can use the API as the authenticated user
api = tweepy.API(auth)

# Post a tweet
status = "Hello, world! This is my second automated tweet via Tweepy!"
api.update_status(status=status)

print("Tweet successfully posted!")
