response.elapsed – 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.elapsed out of a response object. response.elapsed returns a timedelta object with the time elapsed from sending the request to the arrival of the response. It is often used to stop the connection after a certain point of time is “elapsed”.

Advanced Concepts

There are many libraries to make an HTTP request in Python, which are httplib, urllib, httplib2, treq, etc., but requests is the one of the best with cool features. If any attribute of requests shows NULL, check the status code using below attribute.

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.
