Multiple Inheritance in Python

Duck(Flyer, Swimmer) gets methods from both. MRO decides who wins if names clash.

3class Flyer:
4    def fly(self):
5        print("Can fly")

7class Swimmer:
8    def swim(self):

11class Duck(Flyer, Swimmer):
12    pass

14d = Duck()
15d.fly()
16d.swim()

Output

Can fly
Can swim

What's going on

Duck inherits behaviors from both Flyer and Swimmer via multiple inheritance.
