Python Coding challenge - Day 124 | What is the output of the following Python Code?

 

Code:

class Circle:

    pass

Circle.pi = 3.14

print(Circle.pi)

Circle.pi = 3.1415

Answer and Solution:

The above code defines a simple class named Circle and assigns a value to its attribute pi. Here's a breakdown of the code:

class Circle:

    pass

This code declares a class named Circle with no attributes or methods. It's an empty class, indicated by the pass statement.

Circle.pi = 3.14

This line adds a class attribute pi to the Circle class and assigns the value 3.14 to it. In Python, you can dynamically add attributes to a class at runtime.

print(Circle.pi)

This line prints the value of the pi attribute of the Circle class, which is 3.14 as assigned in the previous line.

Circle.pi = 3.1415

This line updates the value of the pi attribute for the Circle class to 3.1415.

If you were to print the value of Circle.pi again after this line, it would now display 3.1415 instead of the initial value 3.14.
