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'))

Answer 1

您的错误在第 3 行：

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 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'))
