1. 写一个求正方形周长和面积的类

 1 class Square:
 2     def __init__(self, length):
 3         self.length = length
 4     def area(self):
 5         return '边长为{}的正方形的面积为：{}'.format(self.length, self.length**2)
 6     def perimeter(self):
 7         return '边长为{}的正方形的周长为：{}'.format(self.length, self.length * 4)
 8 z1 = Square(5)
 9 print(z1.area())
10 print(z1.perimeter())

 

2. 完成人狗大战

 1 class Dogs:
 2     def __init__(self,name,HP,aggr,kind):
 3         self.name = name
 4         self.HP = HP
 5         self.aggr = aggr
 6         self.kind = kind
 7 
 8     # 狗：攻击技能（咬人）
 9     def bite(self,person):
10         # 狗咬人，人掉血
11         person.HP -= self.aggr
12         if person.HP <= 0:
13             print('%s被%s咬死了, 扑街...') % (person.name, self.name)
14         else:
15             print('%s被%s咬了, 掉了%s滴血, 还剩%s滴血' % (person.name, self.name ,self.aggr,person.HP))
16 
17 class Person:
18     def __init__(self,name,HP,aggr,sex):
19         self.name = name
20         self.HP = HP
21         self.aggr = aggr
22         self.sex = sex
23 
24     # 人：攻击技能（打）
25     def attack(self,dog):
26         dog.HP -= self.aggr
27         if dog.HP <= 0:
28             print('%s被%s打死了, 扑街...' % (dog.name, self.name))
29         else:
30             print('%s被%s打了, 掉了%s滴血, 还剩%s滴血' % (dog.name, self.name ,self.aggr,dog.HP))
31 
32 
33 jin = Dogs('二狗', 300, 1, '泰迪')
34 alex = Person('人', 200, 500, '不详')
35 jin.bite(alex)              # Dogs.bite(jin,alex)
36 alex.attack(jin)
