python 类的例子

题目描述

创建三个类：人类、枪类、弹夹类，实现人打枪，弹夹设置弹容量，随着子弹的减少显示弹夹内剩余子弹数

源代码

class People():
    def __init__(self,gun):
        self.gun = gun
    def fire(self):
        gun.shoot()
class Gun():

def init(self,bulletBox):

self.bulletBox = bulletBox

def shoot(self):

bulletBox.bulletNum -=1

print("子弹剩余%d发" % bulletBox.bulletNum)

if bulletBox.bulletNum == 0:

print("没子弹了，请重新装弹")
class BulletBox():

def init(self,bulletNum):

self.bulletNum = bulletNum

bulletNum = int(input("请输入子弹个数："))

if bulletNum >= 7:

print("只能装填7发子弹")

else:

bulletBox = BulletBox(bulletNum)

gun = Gun(bulletBox)

pro = People(gun)

while 1:

pro.fire()

if bulletBox.bulletNum == 0:

break
