Pattern: Unsubscriptable object
Issue: -
Emitted when a subscripted value doesn't support subscription (i.e. doesn't define __getitem__ method).
Example of incorrect code:
class NonSubscriptable(object):
pass
NonSubscriptable()[0] # [unsubscriptable-object]
NonSubscriptable[0] # [unsubscriptable-object]Example of correct code:
class Subscriptable(object):
def __getitem__(self, key):
return key + key
Subscriptable()[0]
