Python __class__ Attribute : Design Patterns In Python
Channel Membership : / @sbcode
Documentation : https://sbcode.net/python/proxy/#__cl...
You can change the class of an object by executing self.__class__ = SomeOtherClass
Note that doing this does not affect any attributes created during initialisation, eg self.instance_attribute = 'abc' , since the object itself hasn't changed. Only the references to it's methods and static attributes have been replaced with the methods and static attributes of the new class.
This explains how calling tell_me_the_future() and tell_me_your_form() from the Proxy use case example, produced different results after changing self.__class__
(Book) Sometimes you just want to switch off your computer and read from a book. So, all GoF patterns are discussed in my Design Patterns In Python book
