SocketErrors

SocketErrors contains exceptions that may be raised while working with the socket module.

StrictHTTPErrors

StrictHTTPErrors contains exceptions that may be raised while working with the http module and some common modules that use it (such as urllib and requests). This grouping only contains exceptions that are clearly not the result of code. They may be caused by an infrastructure or configuration problem and are often temporary.

StrictHTTPErrors is a superset of SocketErrors.

AmbiguousHTTPErrors

AmbiguousHTTPErrors contains exceptions that may be raised while working with the http module and some common modules that use it (such as urllib and requests). This grouping contains exceptions that may or may not be caused by code. The most common reason for this ambiguity is that they are the result of an HTTP response with a 4xx or 5xx status. It is recommended to handle 4xx and 5xx responses separately. 4xx responses are often caused by unvalidated user input or another code issue. 5xx responses are often caused by temporarily unavailability in a dependent service.

HTTPErrors

StrictHTTPErrors contains exceptions that may be raised while working with the http module and some common modules that use it (such as urllib and requests).

HTTPErrors is a superset of StrictHTTPErrors and AmbiguousHTTPErrors.

Combining Errors

Exception groups provided by neterr can be combined with other exceptions using the add operator.

from neterr import HTTPErrors

try:
    raise MyException()
except HTTPErrors + MyException:
    print('caught!')

try:
    raise MyException()
except HTTPErrors + (MyException, MyOtherException):
    print('caught!')

try:
    raise MyException()
except HTTPErrors + [MyException, MyOtherException]:
    print('caught!')
