First Time using and API, how do I get started with=

I learned now that I need to use the Client ID and Secret in order to obtain the OAuth token, and I have done so using CUrl, but now I’d like to be able to get the token through python Requests. Here is the code I have so far, CLIENT_ID is set to my client ID. When I call the function, the response returns “error 400, missing client ID”.
