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：
- 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；
- 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。
