class

class Dog:
	cute = True
	def have_it(doggy):
		print('eating')

Class instantiation

Call syntax ： Instance name = Class name （）
significance ： We have a specific example , It can call all properties and methods of its class .

class Dog:
	cute = True		# Here are the properties   Dog hook cute yes True
	def have_it(doggy):		# Here's the method （ Functions in a class are called methods ）
		print('eating')

a = Dog()		# Class instantiation 
print(a.cute)		# Print classes are properties 
a.have_it()		# Method of calling class 
print(a)

Create a class —— Class instantiation —— Call the properties and methods of the class with an instance .

Create a class ~~class Class name ：
Writing properties of a class
Write methods in classes （ function ）

Class instantiation ~ Variable name = Class name （）
Instance name . attribute
Instance name . Method （）
