参考代码1

class Stu:
	def __init__(self,name,weight):
		self.__name=name
		self.__weight=weight
 
	@property	
	def Name(self):
		return self.__name
 
	@property	
	def Weight(self):
		return self.__weight
 
	def __add__(self,obj):
		sN=self.Name+" "+obj.Name
		sW=self.Weight+obj.Weight
		newS=Stu(sN,sW)
		return newS
 
	def __str__(self):
		print("Name:"+self.__name+" Weight:"+str(self.__weight))
		return ""
 
s1=Stu("张三",100)
s2=Stu("李四",80)
s3=s1+s2
print(s1)
print(s2)
print(s3)
print(s3.Name)
print(s3.Weight)
print(s3)
