Python printing None in result , Why?

I am trying to understand Classes in python.

Question: Why I am getting None in the output?

Here is my code :

class Student:

    def __init__(self, name, age):
        self.name = name
        self.age = age

    def show_student(self):
        print("Student Name:", self.name)
        print("Student Age: ", self.age)


first_student = Student("amit", 12)
print(first_student.show_student())

And here is the output.

C:\Python38\python.exe D:/LearningRoot/DirFirst/test.py
Student Name: amit
Student Age:  12
None

>Solution :

first_student.show_student() returns None, which is what all Python functions return if no explicit return value was specified. Therefore:

print(first_student.show_student())

This will evaluate to print(None).
