Tag: metaclasses, Python classes

Metaclasses in Python define how classes behave. They are the ‘classes of classes’ and allow you to customize class creation and inheritance.

Example of a metaclass:

class Meta(type):
    def __new__(cls, name, bases, dct):
        dct['greeting'] = 'Hello'
        return super().__new__(cls, name, bases, dct)

class MyClass(metaclass=Meta):
    pass

print(MyClass.greeting)  # Hello
