Python method resolution order: Inheriting methods from a parent

Thanks to ICPO/MRO, if a child Python class doesn’t define a method, the parent method will be invoked:

class Parent:
    def x(self):
        return 'x from Parent'

class Child(Parent):
    pass

c = Child() 

# x isn't on c
# x is on c's class
c.x() # 'x from Parent'
