bookMethod Resolution Order

Method Resolution Order is an order of searching the attributes/methods from Parent classes.

To check this order, you can use the mro() built-in method:

12345678910111213141516
class A: pass class B: pass class C(B): pass class D(A): pass class Child(C, D): pass print(Child.mro())
copy

The mro() method returns a list of classes that represents the method and attribute search order.

Note

The mro() method can be called via classes, not for instances.

123456789
print(int.mro()) print(float.mro()) print(bool.mro()) print(str.mro()) class SomeClass: pass print(SomeClass.mro())
copy

Note

Pay attention: all objects in Python are inherited from the object class.
