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.headers out of a response object. response.headers returns a dictionary of response headers. To check more about headers, visit – Different HTTP Headers

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.
