1"""Exception classes raised by urllib. 

2 

3The base exception class is URLError, which inherits from OSError. It 

4doesn't define any behavior of its own, but is the base class for all 

5exceptions defined in this package. 

6 

7HTTPError is an exception class that is also a valid HTTP response 

8instance. It behaves this way because HTTP protocol errors are valid 

9responses, with a status code, headers, and a body. In some contexts, 

10an application may want to handle an exception like a regular 

11response.
