Python SDK V2 OAuth Problem/Question

Python SDK V2 OAuth Problem/Question

Hello there,

I´m new to python, so I apologize if my questions is dumb. I also searched everywhere but I cannot find a solution or an answer. 

First of all: I used this documentation for CRM SDK v2: https://www.zoho.com/crm/developer/docs/python-sdk/v2/config.html
I installed zohocrmsdk2-0          4.0.0

Initializing the sdk works. But when I try to actually do something, i get an OAuth error:

Status Code: 401
Status: error
Code: INVALID_TOKEN
Details
Message: invalid oauth token

I guess I need help or an explanation regarding this part:
  1. from zcrmsdk.src.com.zoho.api.authenticator.oauth_token import OAuthToken

    """
    Create a Token instance that takes the following parameters
    1 -> OAuth client id.
    2 -> OAuth client secret.
    3 -> Grant token.
    4 -> Refresh token.
    5 -> OAuth redirect URL. Default value is None
    6 -> id
    7 -> Access token
    """
    token = OAuthToken(client_id='clientId', client_secret='clientSecret', grant_token='grant_token', refresh_token="refresh_token", redirect_url='redirectURL', id="id", access_token="access_token")
How do I use this? 
When using the API Console I only get clientId, clientSecret and Grant_token. Do I paste these strings as arguments instead of 'clientId', 'clientSecret' and 'grant_token'?
Does the SDK then get the access and refresh tokens? Or do I have to create them another way?
Also, what is 6 -> id?

The documentation does not tell how to use this at all.

Thank you for your help.
