Question

我正在创建具有以下条件的if语句：如果date_today> =过期日期： expiredate是字典的字符串格式输出。我试图将其格式化为日期时间，以便可以检查它是否大于或等于今天：

import datetime
from datetime

date_today = datetime.date.today()

for list in dict: # Getting the data out of a list of dicts    
    expiringdate = list.get('expiredate')  # Retrieving the expiredate strings.
    expiredate = datetime.datetime.strftime(expiringdate, '%Y-%m-%d') # Setting the expiredate variable to a datetime format. 
    if date_today >= expiredate:  # Checking if the date is greater then or equal to the other date.
        print('yeah it worked')
    else:
        print('it didn't work')

我收到以下错误消息。

expiredate = datetime.datetime.strftime(expiredate, '%Y-%m-%d')
TypeError: descriptor 'strftime' requires a 'datetime.date' object but received a 'str'

我只想检查今天的日期是否大于或等于到期日期。但是我无法弄清楚。

如果expiredate是字符串，则需要使用strptime：

from datetime import datetime as dt

dt.strptime("2019-07-31", "%Y-%m-%d")

比较日期未按预期进行
