how to make a class in python

1class Mammal:
2    def __init__(self, name):
3        self.name = name
4
5    def walk(self):
6        print(self.name + " is going for a walk")
7
8
9class Dog(Mammal):
10    def bark(self):
11        print("bark!")
12
13
14class Cat(Mammal):
15    def meow(self):
16        print("meow!")
17
18
19dog1 = Dog("Spot")
20dog1.walk()
21dog1.bark()
22cat1 = Cat("Juniper")
23cat1.walk()
24cat1.meow()

1class Person:
2  def __init__(self, _name, _age):
3    self.name = _name
4    self.age = _age
5   
6  def sayHi(self):
7    print('Hello, my name is ' + self.name + ' and I am ' + self.age + ' years old!')
8    
9p1 = Person('Bob', 25)
10p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old!

1# To create a simple class:
2class Shape:
3  	def __init__():
4      	print("A new shape has been created!")
5      	pass
6    
7    def get_area(self):
8		pass
9
10# To create a class that uses inheritance and polymorphism
11# from another class:
12class Rectangle(Shape):
13  
14	def __init__(self, height, width): # The constructor
15    	super.__init__()
16        self.height = height
17    	self.width = width
18
19	def get_area(self):
20      	return self.height * self.width
21

1class uneclasse():

7xx.something()

1class Person:#set name of class to call it

5   
6
7    def myfunc(self):#func inside of class 
8      print("Hello my name is " + self.name)# code that the func dose
9
10p1 = Person("barry", 50)# setting a ver fo rthe class 
11p1.myfunc() #call the func and whitch ver you want it to be with 

1class Fan:
