It is used to provide an interface for Requests sessions to connect with HTTP and HTTPS. This will help us to mimic the web service to fit our needs. With the help of Transport Adapters, we can configure the request according to the HTTP service we opt to use. Requests contains a Transport Adapter called HTTPAdapter included in it.

Consider the following example:

>>> session = requests.Session()
>>> adapter = requests.adapters.HTTPAdapter(max_retries=6)
>>> session.mount("http://google.co.in", adapter)

In this example, we created a request session in which every request we make retries only six times, when the connection fails.
