response.history – Python requests
Python requests are generally used to fetch the content from a particular resource URI. Whenever we make a request to a specified URI through Python, it returns a response object. Now, this response object would be used to access certain features such as content, headers, etc. This article revolves around how to check the response.history out of a response object. response.history returns a list of response objects holding the history of request (url). Basically, it shows how did the request reach the target in form of a list of responses.

requests.status_code
If status_code doesn’t lie in range of 200-29. You probably need to check method begin used for making a request + the url you are requesting for resources.
