1 问题

在python中我们常常使用到条件判断,if语句时常见的条件判断语句之一。那么如何使用if语句实现根据情况自动选择商品进行售卖呢?

2 方法

根据if语句执行时从上往下执行的特点,使用if语句、dict和list来实现整个流程

代码清单 1

代码语言:javascript复制
drinks = {'greentea':'please pay 4','weaktea':'please pay 5','blackcffee':'please pay 7','coffeewithmilk':'please pay 9','cocoa':'please pay 6'}
drink = input('please input you wanted drink:')
L=['greentea','weaktea','blackcffee','coffeewithmilk','cocoa']
if drink == l[0]:
   print( drinks['greentea'])
elif drink == l[1]:
   print( drinks['weaktea'])
elif drink == l[2]:
   print( drinks['blackcffee'])
elif drink == l[3]:
   print( drinks['coffeewithmilk'])
elif drink == l[4]:
   print( drinks['cocoa'])
else:
   print('There is no drink you want')

3 结语

针对用python实现自主售卖机问题,提出if语句的方法,通过运用if语句、dict和list实验,证明该方法是有效的,但本文的方法单一,可实现的成果简单单一,未来可以在此基础上扩展自主售卖机的功能。
