python 练习题4

现在IPV4下用一个32位无符号整数来表示，一般用点分方式来显示，点将IP地址分成4个部分，每个部分为8位，表示成一个无符号整数（因此不需要用正号出现），如10 .137.17.1，是我们非常熟悉的IP地址，一个IP地址串中没有空格出现（因为要表示成一个32数字）。
现在需要你用程序来判断IP是否合法。
输入描述:输入一个ip地址
输出描述:返回判断的结果YES or NO
示例1
输入: 10.138.15 .1
输出: YES

#!/usr/bin/env python
#coding:utf-8
ip=raw_input("IP:")
list=ip.split(".")
if len(list) != 4:
    print 'NO'
else:
    for i in list:
        if not 0<=int(i)<=255:
            print 'no'
            break
    else:
        print'YES'

考生需要模拟实现一个简单的自动售货系统，实现投币、购买商品、退币、查询库存商品及存钱盒信息的功能。
系统初始化时自动售货机中商品为6种商品, 商品的单价自定义，存钱盒内放置1元、2元、5元、10元钱币，商品数量和钱币张数通过初始化命令设置。
商品:每种商品包含商品名称、单价、数量三种属性，其中商品名不重复。不能修改商品名称和单价，初始化命令设置商品数量。
