python的基本操作if else

money = input("输入你的钱数")
money = int(money) #这是为了money转换成int类型,因为只要用过input函数获取的内容变量永远都是str类型
if money > 500:
    print("大吃大喝去")
elif money > 300:
    print("吃水果喝啤酒")
elif money > 50:
    print("吃个盖饭")
else:
    print("太穷了")
lst = ["abc","bcd","cde","def","efg"]
str = input("请输入你想验证的字符串 : ").lower()
if str in lst :
    print("Yes")
else :
    print("No")
#验证某些特定的值不在列表中,用到的是not in
str = input("请输入你想验证的字符串 : ").lower()
if str not in lst :
    print("Yes")
else :
    print("No")
