How python defines classes

This article will explain in detail how to define classes in python. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Common method

There are two ways to create a common method (class A () & class B ()).

Class A (): def _ init__ (self, name, age): self.name = name self.age = age def get_name (self): print ('my name is', self.name) def get_age (self): print (Flemi am {self.age} years old') class B (): def get_name (self, name): print ('my name is', name) def get_age (self Age): print (Flemi am {age} years old') if _ _ name__ ='_ _ main__': a = A ('tom',19) a.get_name () # my name is tom a.get_age () # I am 19 years old b = B () b.get_name (' tom') # my name is tom b.get_age (19) # I am 19 years old

In class A (), _ _ init__ () is a special method, which is equivalent to initializing A. the self in _ _ init__ is the object An itself, and name and age are their formal parameters.

The class needs to be instantiated before each method call
