我如何在python中獲取時間間隔

Question

現在我有時間： a=2015-02-23 03:56:00 b=2015-02-23 02:56:00而且在c很多時間，我該如何選擇這段時間的時間

for d in c :

  if (a >= d>= b):

     print d

我的結果：

2015-02-23 13:09:00

2015-02-23 12:09:00

2015-02-23 12:09:00

結果是錯誤的！

Answer 1

from datetime import datetime
start = datetime.strptime("2015-02-23 02:56:00","%Y-%m-%d %H:%M:%S")
end = datetime.strptime("2015-02-23 03:56:00","%Y-%m-%d %H:%M:%S")

if start <= d <= end:
    print(d)

我還重命名了變量以使其更加明顯，您的時間必須在> =開始時間而<=結束時間在范圍內。

In [1]: from datetime import datetime 
In [2]: start = datetime.strptime("2015-02-23 02:56:00","%Y-%m-%d %H:%M:%S")

In [3]: end = datetime.strptime("2015-02-23 03:56:00","%Y-%m-%d %H:%M:%S")

In [4]: d = datetime.strptime("2015-02-23 13:09:00","%Y-%m-%d %H:%M:%S")

In [5]: start <= d <= end
Out[5]: False

In [6]: d = datetime.strptime("2015-02-23 12:09:00","%Y-%m-%d %H:%M:%S")

In [7]: start <= d <= end
Out[7]: False

In [8]: d = datetime.strptime("2015-02-23 02:59:00","%Y-%m-%d %H:%M:%S")

In [9]: start <= d <= end
Out[9]: True
