1.编写程序, 编写一个学生类, 要求有一个计数器的属性, 统计总共实例化了多少个学生
class Student: count=0 def __init__(self,name,age,gender): self.name=name self.age=age self.gender=gender Student.count+=1 ming=Student("小明",25,"male") hong=Student("小红",25,"female") lan=Student("小兰",25,"female") print(Student.count)2、人狗大战
class Person: def __init__(self,name,aggr,hp,level): self.name=name self.aggr=aggr self.hp=hp self.level=level def atta(self,dog): dog.hp-=self.aggr print("%s踢了一脚%s,%s掉了%s点血" % (self.name, dog.name, dog.name, self.aggr)) class Dog: def __init__(self,name,aggr,hp,kind): self.name=name self.aggr=aggr self.hp=hp self.kind=kind def bite(self,person): person.hp-=self.aggr print("%s咬了一口%s,%s掉了%s点血"%(self.name,person.name,person.name,self.aggr)) guo=Dog("果果",25,100,"金毛") ming=Person("小明",25,100,15) guo.bite(ming) ming.atta(guo) print(ming.__dict__) print(guo.__dict__)3、正方形周长和面积
class Square: def __init__(self,r): self.side=r def peri(self): return "周长是%s"%(4*self.side) def area(self): return "面积是%s"%(self.side**self.side) s=Square(2) print(s.peri()) print(s.area())
