Errors and exceptions

Requests throws an exception when a network problem is encountered, such as a DNS query failure, a denial of connection, and so on ConnectionError .

When a rare invalid HTTP response is encountered, requests throws an HTTPError exception.

If the request times out, an Timeout exception is thrown.

If the request exceeds the set maximum number of redirects, an exception is thrown TooManyRedirects .

All exceptions that are explicitly thrown by requests inherit from requests.exceptions.RequestException .
