Python Metaprogramming Development Tutorials, Guides & Insights

• Use __init_subclass__ to debug subclass creation instead of overriding the metaclass.

class DebugBase:
    def __init_subclass__(cls, **kwargs):

        super().__init_subclass__(**kwargs)

class Subclass(DebugBase):
    pass
# Output: Creating subclass Subclass
