在python中以分鍾為單位獲取兩個日期時間對象之間的差異

Question

我有兩個由strptime在Python中創建的日期時間對象：

date_string = "Wed, 18 Dec 2013 09:30:00 GMT"
date = datetime.datetime.strptime(date_string, "%a, %d %b %Y %H:%M:%S %Z")

和

end_date_string = "Wed, 18 Dec 2013 10:15:00 GMT"
end_date = datetime.datetime.strptime(end_date_string, "%a, %d %b %Y %H:%M:%S %Z")

我成功創建了日期時間對象

>>>date
datetime.datetime(2013, 12, 18, 9, 30)
>>>end_date
datetime.datetime(2013, 12, 18, 10, 15)

我想計算兩個日期時間不同的分鍾數。 我做

diff = end_date - date   

我明白了

 datetime.timedelta(0)

所以它說它們是相同的日期？沒有任何區別？ 秒屬性為零

>>>diff.seconds
0

怎么能這樣做？

Answer 1

import datetime

date_string = "Wed, 18 Dec 2013 09:30:00 GMT"
date = datetime.datetime.strptime(date_string, "%a, %d %b %Y %H:%M:%S %Z")
end_date_string = "Wed, 18 Dec 2013 10:15:00 GMT"
end_date = datetime.datetime.strptime(end_date_string, "%a, %d %b %Y %H:%M:%S %Z")
print (end_date-date).total_seconds()

給

2700.0

Answer 2

這有點奇怪，我得到了正確的結果：

>>> date_string = "Wed, 18 Dec 2013 09:30:00 GMT"
>>> date = datetime.datetime.strptime(date_string, "%a, %d %b %Y %H:%M:%S %Z")
>>> end_date_string = "Wed, 18 Dec 2013 10:15:00 GMT"
>>> end_date = datetime.datetime.strptime(end_date_string, "%a, %d %b %Y %H:%M:%S %Z")
>>> diff = end_date - date
>>> diff
datetime.timedelta(0, 2700)
>>> diff.seconds
2700

這是整個代碼嗎？
