写这个程序的时候,我已学习Python将近有一百个小时,在CSDN上看到有人求助使用Python如何写一个自动售饮料的程序,我一想,试试写一个实用的售货程序。当然,只是实现基本功能,欢迎高手指点,新手学习参考。

运行环境:Python 2.7

loop=True
money=0
while loop:
    x = raw_input('提示:请投入金币,结束投币请按"q"键')
    if x=='q':
        if money==0:
            print '错误:您未投入过纸币,请至少投入一张纸币后才能选购商品'
        else:
            print '提示:您已结束投币,将进入购买商品操作界面'
            loop = False
    else:
        try:
            x = int(x)
            money+=x
            print '提示:您此次投币',x,'元人民币,您一共投币',money,'元人民币'
        except Exception,e:
            print '错误:您的金币系统不识别,请重新投币,谢谢!'
 
GoodList = {
    '可口可乐':2.5,
    '果粒橙':3,
    '奶茶':1.5,
    '加多宝':4
}
 
i=0
print '请选择商品:'
for x in GoodList:
    i+=1
    print '编号',i,'商品名称',x,'价格',GoodList[x]
print
 
fanwei = range(len(GoodList))
loop = True
while loop:
    o = raw_input('提示:请输入您要购买的商品编号,按"q"键结束购买')
    if o=='q':
        loop = False
    else:
        try:
            o = int(o)
            if o>=1 and o<=len(GoodList):
                i=0
                for x in GoodList:
                    i+=1
                    if i==o:
                        if money>=GoodList[x]:
                            money -= GoodList[x]
                            print '提示:您购买的商品是:',x,',价格:',GoodList[x],',您还剩余:',money,'元人民币'
                            if money==0:
                                loop = False
                        else:
                            print '错误:您的余额',money,'元已不足购买此商品',x,'[',GoodList[x],'元]'
            else:
                print '错误:您输入的商品编号不存在,请重新输入'
        except Exception,e:
            print '错误:请输入正确的产品编号,谢谢合作!'
 
if money>0:       
    print '提示:系统将找您,',money,'元人民币,欢迎下次光临'
else:
    print '提示:您的余额已用完,欢迎下次光临'
