The __init__() Function:

classes and objects in their simplest form are not really useful in real life applications. It's a built-in __init__() function. 

Example :        

Use the __init__() function to assign values for name and age:

class Person: 
  def __init__(self, name, age):

    self.name = name

    self.age = age

p1 = Person("Prakash", 19)

print(p1.name)

print(p1.age)
