练习：要求输入一个四位数的年，判断当前的年份的生肖
生肖纪年顺序为：子鼠、丑牛、寅虎、卯兔、辰龙、巳蛇、午马、未羊、申猴、酉鸡、戌狗、亥猪
year = int(input('输入一个四位数的年'))
print(year)
#地支算法：用公元纪年-3，除以12所得余数，即为对应的年
if (year-3)%12 == 0:
print('猴年')
elif(year-3)%12 == 1:
print('鸡年')
elif(year-3) == 2:
print('狗年')
elif(year-3)%12 == 3:
print('猪年')
elif (year - 3) % 12 == 4:
print('鼠年')
elif (year - 3) % 12 == 5:
print('牛年')
elif (year - 3) % 12 == 6:
print('虎年')
elif (year - 3) % 12 == 7:
print('兔年')
elif (year - 3) % 12 == 8:
print('龙年')
elif (year - 3) % 12 == 9:
print('蛇年')
elif (year - 3) % 12 == 10:
print('马年'）
elif(year - 3) % 12 == 11:
print('羊年')
else:
print("输入错误")
简化版
year = int(input('输入一个四位数的年份:'))
print(year)
varlist = ['申猴','酉鸡','戌狗','亥猪','子鼠','丑牛','寅虎','卯兔','辰龙','巳蛇','午马','未羊']
print(varlist[year%12])
