How To Make a Subclass from a Super Class In Python

# super class
class Base:
    # constructor to initialize attributes
    def __init__(self, name, roll, age):
        self.name = name
        self.roll = roll
        self.age = age
# sub class
class Sub(Base):
    # constructor to initialize attributes of both Base and Sub class
    def __init__(self, name, roll, age):
        super().__init__(name, roll, age)
    # method to display information
    def display(self):
        print(f" Name: {self.name}\n Roll: {self.roll}\n Age: {self.age}")
# creating an object of Sub class
obj = Sub("Sonali", 58, 24)
obj.display()

# Superclass
class Base:
    def __init__(self, name, roll, age):
        self.name = name
        self.roll = roll
        self.age = age
# Create a subclass using type.__new__
Sub = type("Sub", (Base,), {})
# Creating an object of the Subclass with data
obj = Sub("Sonali", 58, 24)
# Displaying information
print(f" Name: {obj.name}\n Roll: {obj.roll}\n Age: {obj.age}")

from collections import namedtuple
# Superclass using namedtuple
Base = namedtuple('Base', ['name', 'roll', 'age'])
# Subclass with additional attribute
class Sub(Base):
    def __new__(cls, name, roll, age, extra):
        obj = super(Sub, cls).__new__(cls, name, roll, age)
        obj.extra = extra
        return obj
# Creating an object of the Subclass with data
obj = Sub("Sonali", 58, 24, "Additional Info")
# Displaying information
print(f" Name: {obj.name}\n Roll: {obj.roll}\n Age: {obj.age}\n Extra: {obj.extra}")
