Diamond Problem in Python

Last Updated : 23 Jul, 2025

Diamond problem is also known as the "Deadly Diamond of Death", This problem mainly occurs in object-oriented programming in Python. It mainly arises when a class inherits from two or more classes that themselves share a common superclass. This situation creates ambiguity in the inheritance hierarchy, leading to confusion about which properties or methods of the shared superclass should be inherited.

In this article, we will understand What is Diamond Problem in Python and How we can solve this problem.

Diamond Shape inheritance

Diamond Shape Inheritence

• Shape: The common superclass representing general properties and behaviors of a shape.
• Circle: Intermediate subclasses that inherit from Shape, each adding specialized attributes or behaviors
• Square: Intermediate subclasses that inherit from Shape, each adding specialized attributes or behaviors.
• Cylinder: A subclass that inherits from both Circle and Square, potentially combining their attributes and behaviors.

Here's how this hierarchy looks in Python:

class shape:

    def display(self):

        print("class shape")

​

class circle(shape):

    def display(self):

        print("class circle")

​

class square(shape):

    def display(self):

        print("class square")

​

class cylinder(circle, square):

    pass

​

obj = cylinder()

obj.display()  # Calls circle's display method

Output

class circle
