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)

I also renamed your variables to make it a little more obvious, your time needs to be >= the start time and <= the end time to be in the range.

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
