类与类之间的关系
1. 依赖关系
class Plant: def __init__(self,zhonglei,xue,gongjili): self.zhonglei = zhonglei self.xue = xue self.gongjili = gongjili def da(self,js): print("植物打僵尸") js.xue -= self.gongjili if js.xue <= 0: print("僵尸死亡") else: print(f"僵尸掉血{self.gongjili},僵尸还剩{js.xue}血") class Jiang: def __init__(self,zhonglei,xue,gongjili): self.zhonglei = zhonglei self.xue = xue self.gongjili = gongjili def chi(self,zw): print("僵尸咬植物") zw.xue -= self.gongjili if zw.xue <= 0: print("植物死亡") else: print(f"植物掉血{self.gongjili},植物还剩{zw.xue}血") p = Plant("豌豆",1000,300) j = Jiang("路障",1800,200) p.da(j) p.da(j) p.da(j) p.da(j) j.chi(p) j.chi(p) p.da(j) j.chi(p) j.chi(p) p.da(j) 2. 关联关系
class Boy: def __init__(self, name, girlFriend=None): self.girlFriend = girlFriend # 一个男孩有一个女朋友 def chi(self): if self.girlFriend: print(f"带着他的女朋友{self.girlFriend.name}去吃饭") else: print("单身狗, 吃什么吃? 滚去学习.") class Girl: def __init__(self, name): self.name = name b = Boy("宝宝") g = Girl("孙艺") b.chi()
self.teach_list = [t1,t2,t3]
class School: def __init__(self, name): self.teach_list = [] # 这里要装多个老师 self.name = name def zhaopin(self, teach): self.teach_list.append(teach) def shangke(self): for t in self.teach_list: t.work() class Teacher: def __init__(self, name): self.name = name def work(self): print(f"{self.name}在上课") s = School("蓝翔") t1 = Teacher("老师1") t2 = Teacher("老师2") t3 = Teacher("老师3") s.zhaopin(t1) s.zhaopin(t2) s.zhaopin(t3) s..shangke() 类中的关系: 依赖关系是最轻的. 最重的是继承关系. 关联关系是比较微妙的.
