Access parent class instance attribute from child class instance?

How to access "myvar" from "child" in this code example:

class Parent():
    def __init__(self):
        self.myvar = 1

class Child(Parent):
    def __init__(self):
        Parent.__init__(self)

        # this won't work
        Parent.myvar

child = Child()
Solution

  • Parent is a class - blue print - not an instance of it. In OOP, to access attributes of an object, it requires an instance of the same.

    Here self/child are instances while Parent/Child are classes.

    class Parent():
    def __init__(self):
        self.myvar = 1

class Child(Parent):
    def __init__(self):
        Parent.__init__(self)

        # here you can access myvar like below.
        print self.myvar

child = Child()
print child.myvar
