python - 如何匹配时间数据 ' 01/27/1998' 到 '%d/%m/%y' 之间的格式？

Question

我只是想显示我的生日(dd/mm/yyyy)。然后，我得到了“ValueError”就像“时间数据 %r 与格式 %r 不匹配”% 和“时间数据 '01/27/1998' 与格式 '%d/%m/%y' 不匹配”

这是我的代码

from datetime import datetime, timedelta

birthday = input('When is your birthday (dd/mm/yyyy)?')

birthday_date = datetime.strptime(birthday, "%d/%m/%y")

print('Birthday : ' + str(birthday_date))

one_day = timedelta(days=1)
birthday_eve = birthday_date - one_day
print('Day before birthday : ' + str(birthday_eve))

这是错误的详细信息

When is your birthday (dd/mm/yyyy)? 01/27/1998
Traceback (most recent call last):
  File "010-input_date.py", line 5, in <module>
    birthday_date = datetime.strptime(birthday, "%d/%m/%y")

    tt, fraction, gmtoff_fraction = _strptime(data_string, format)

    raise ValueError("time data %r does not match format %r" %
ValueError: time data ' 01/27/1998' does not match format '%d/%m/%y'

Answer 1

它必须是'%d/%m/%Y'，因此请替换以下行:

birthday_date = datetime.strptime(birthday, "%d/%m/%y")

与:

birthday_date = datetime.strptime(birthday, "%d/%m/%Y")
