#题目：输入某年某月某日，判断这一天是这一年的第几天？
data = input('输入年月份,格式2016-05-12:')
#字符串切割
s = data.split("-")#以-为标志切割
if(len(s == 3)):
#赋值
year = int(s[0])

print (mon)
# python没有switch case 用字典方式

da={'1':0,'2':31,'3':59,'4':90,'5':120,'6':151,'7':181,'8':212,'9':243,'10':273,'11':304,'12':334}

if(year %400 == 0 or (year %4 == 0 and year %100 != 0)):

sum += 1
print(sum)
运行然后报错
