Child class inheritance issue

[eakanathan]

class A:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    def details(self):
        print (self.name)
        
obj = A('Ramesh', 62)
obj.details()

class B:
    def __init__(self, name, id):
        self.name = name
        self.id = id
    def details1(self):
        print (self.name)
obj = B('Ram', 1234)
obj.details1()

class C(A,B):
    print("Just inside class C")
    
    def __init__(self):
        A.__init__(self)  # calling class A constructor
        print('Calling Class A constructor')
       
        
    def get_details(self):
        A.details(self)
        print(A.details(self.name))

Class A and B output are fine. When I try with class C, it prints "just inside class C", after that no output, no error message. Where I am missing? Can any one help pl?

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

Please use tags when posting code.
Maybe something like this

class A:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    def details(self):
        print (self.name)

obj = A('Ramesh', 62)
obj.details()

class B:
    def __init__(self, name, id):
        self.name = name
        self.id = id
    def details1(self):
        print (self.name)
obj = B('Ram', 1234)
obj.details1()

class C(A,B):
    print("Just inside class C")

    def __init__(self):
        A.__init__(self, 'name me', 23) # calling class A constructor
        print('Calling Class A constructor')

    def get_details(self):
        A.details(self)
        print(A.details(A.self.name))

obj = C()
obj.details()

Output:
Ramesh
Ram
Just inside class C
Calling Class A constructor
name me

Thanks a ton for immediate response to my very basic in python. Pardon me for asking such questions, but wish to learn on my own. Real pleasure and elated to get immediate response. Thank you once again.
Note: will use tags in future.

This code executes when the class C code is parsed, not when an instance of the class is made.

print("Just inside class C")

I know that classes A, B and C are all just examples, but they are horrible examples. If C inherits from classes A and B, it would be because both A and B have things to offer that are different from each other and C should call the __init__() methods for both A and B.

This is a pretty good, short article about multiple inheritance in Python.
