Question

What is the use of __init__? When is it called? Explain with an example.

Answer 1

__init__ is a special method used to initialise the instance attributes of an object. It is called automatically whenever a new object of the class is created.

class Student:
    def __init__(self, name, marks):
        self.name = name
        self.marks = marks

    def display(self):
        print(self.name, self.marks)


s1 = Student("Riya", 95)  # __init__() is called automatically
s1.display()

Riya 95

Here, Student("Riya", 95) automatically invokes __init__ to initialise name and marks.
