HTTP responses provide us with a way to check the status of the response through status codes. We can read the status code of a response using its status property. The value of 200 is an HTTP status code that tells us that the request is OK:

>>> response.status
200

The 200 code informs us that everything went fine. There are a number of codes, and each one conveys a different meaning. According to their first digit, status codes are classified into the following groups:

• 100: Informational
• 200: Success
• 300: Redirection
• 400: Client error
• 500: Server error

Status codes help us to see whether our response was successful or not. Any code in the 200 range indicates a success, whereas any code in either the 400 range or the 500 range indicates failure in the server.
