クラスメソッドは、これは

になり、クラス内

import random 
import sys 
import os 

class Animal : 
    __name="" 
    __height=0 
    __weight=0 
    __sound=0 

    def __init__(self, name, height, weight, sound): 
     self.__name=name 
     self.__height=height 
     self.__weight=weight 
     self.__sound=sound 

    def set_name(self,name): 
     self.__name =name 
    def get_name(self): 
     return self.__name 
    def set_height(self,height): 
     self.__height =height 
    def get_height(self): 
     return str(self.__height) 
    def set_weight(self,weight):
