If a variable name is not found in the dictionary of the current class, the parent classes are searched for it. The += operator modifies the mutable object in-place without creating a new object. So changing the attribute of one instance affects the other instances and the class attribute ...

The somewhat cryptic output means that the first variable refers to the local first_child() function inside of parent(), while second points to second_child().You can now use first and second as if they’re regular functions, even though you can’t directly access the functions they point...
A nice feature of inheritance is that it often leads to good code reuse since a parent class' functions don't need to be re-defined in any of its child classes. Polymorphism - Because derived objects share the same interface as their parents, the calling code can call any function in ...
