第二章 2.4 可以服用的代码 生肖 p45_2_4_zodiac

代码：

def shengxiao(year):
    zodiac=["鼠","牛","虎","兔","龙","蛇","马","羊","猴","鸡","狗","猪"]
    i= (year-1900)%12
    j=zodiac[i]
    return j

myyear=int(input("Please enter your year until enter 0:"))
while myyear!=0:
    print("Your zodiac is:",shengxiao(myyear) )
    myyear=int(input("Please enter your year until enter 0:"))

　　

效果：

Please enter your year until enter 0:1984
Your zodiac is: 鼠
Please enter your year until enter 0:1992
Your zodiac is: 猴
Please enter your year until enter 0:1983
Your zodiac is: 猪
Please enter your year until enter 0:1981
Your zodiac is: 鸡
Please enter your year until enter 0:1999
Your zodiac is: 兔
Please enter your year until enter 0:1996
Your zodiac is: 鼠
Please enter your year until enter 0:2008
Your zodiac is: 鼠
Please enter your year until enter 0:0

　　

总结：

1. 列表有X元素，就取X的模，这样X[0]，对应第一个元素，X[X-1]对应第X个元素；
2. 这里的循环条件，myyear!=0，一直调用函数，一直输出提示语，直到输入0结束，可以改编成随机点名。
