why do we need class in python code example

Example 1: python class

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age
  def myfunc(self):
    print("Hello my name is " + self.name +".")

p1 = Person("Victor", 24)
p1.myfunc()

Example 2: python class

class MyClass:
    """A simple example class"""
    i = 12345

    def f(self):
        return 'hello world'
