Method resolution in multiple inheritance in Python [duplicate]

Question

I'm trying to understand Method Resolution Order in multiple inheirtance. Here's the code that I'm using.When I try to create the object of class 'ClassC', only the constructor of ClassA is getting called.How is the methods resolved in this case?

class ClassA:
    def __init__(self):
        print "inside a's init"

class ClassB:
    def __init__(self):
        print "inside b's init"

class ClassC(ClassA,ClassB):
    pass

c = ClassC()

Output:

inside a's init

Answer 1

There is a python PEP I believe that covers the MRO algorithm in detail but it's rather complex. Additionally, it's covered in the book Fluent Python. I believe the short story is that it goes from left to right

if you switch to

class ClassC(ClassB,ClassA):
    pass

I bet you would see a change. (update, you will definitely see a change)

Also if you call

help(c)

you should see the mro printed out.
