Pattern: __hash__ does not return integer

Issue: -

Description

Used when a __hash__ method returns something which is not an integer.

Example of incorrect code:

class BadHash(object):
    """ __hash__ returns a dict """

    def __hash__(self):  # [invalid-hash-returned]
        return {}

Example of correct code:

class GoodHash(object):
    """__hash__ returns <type 'int'>"""

    def __hash__(self):
        return 1
