We can pass the values (data) during object creation. It will set custom values for instance variables.

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


# create object
stud = Student("John", 15)
print(stud.name, stud.age)
