Python class instance variables example

Simple example code declared Instance variables inside a class method and print the values after creating an object.

Create an instance of our class with the following values:

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

new_stu = Students("John", 15)

Modify Values of Instance Variables

class Student:
    # constructor
    def __init__(self, name, age):
        # Instance variable = name
        self.age = age

# create object
stud = Student("John", 15)
print('Name:',, 'Age:', stud.age)

# modify instance variable = 'Emma'
stud.age = 15

print('Name:',, 'Age:', stud.age)


Name: John Age: 15
