Python：检查日期是否正确

Question

PYTHON

您好，check_date 代码返回 False - 编码有什么问题？第一个函数检查输入的月份中有多少天，第二个函数检查日期格式是否正确。

'''

def days_in_month(month):

if month == 1 or month == 3 or month == 5 or month == 7 or month == 8 or month == 10 or month == 12:

return month == 31

    else:

        return 30

'''

'''

    def check_date(date):

    day = int(date[0:2])

    month = int(date[2:4])

    year = date[4:6]

    

    if ( (day<=days_in_month(month)) and (0<month<13) ):

        return True

    else:

        return False

'''    

    

print(check_date('011297'))
