Python Coding challenge - Day 860| What is the output of the following Python Code?

Code Explanation:

1. Class X Definition

class X:

    def get(self): return "X"

A class X is created.

It defines a method get() that returns the string "X".

Any object of class X can call get() and receive "X".

2. Class Y Definition

class Y:

    def get(self): return "Y"

Another class Y is defined.

It also has a method get(), but this one returns "Y".

This sets up a scenario where both parent classes have the same method name.

3. Class Z Uses Multiple Inheritance

class Z(X, Y):

Class Z inherits from both X and Y.

Because X is listed first, Python’s Method Resolution Order (MRO) will look into:

Z

X

Y

object

4. Z Overrides get()

    def get(self): return super().get() + "Z"

Z defines its own version of the method get().

super().get() calls the parent version according to MRO.

Since X comes before Y, super().get() calls X.get(), returning "X".

"Z" is then concatenated.

So the final result becomes:

"X" + "Z" = "XZ"

5. Printing the Result

print(Z().get())

Creates an object of class Z.

Calls the overridden version of get().

Which internally calls X’s get() and adds "Z" to it.

Output becomes:

XZ

Final Output

XZ
