从 datetime.timedelta 列表中获取时间

Question

I have calculated the time difference using

datetime.strptime ('End Time', FMT) - datetime.strptime ('Start Time', FMT)

and got the list of strings of the format datetime.timedelta(seconds=1535)

I am stuck on how to get the seconds only out of the list of strings, as the object is not subscriptable, and also if there is a way to calculate the time difference in minutes/hours?

Answer 1

(datetime.strptime ('End Time', FMT) - datetime.strptime ('Start Time', FMT)).total_seconds() 

should do the trick, to get seconds, at least since python 3.2. Please refer to documentation ( https://docs.python.org/3/library/datetime.html#datetime.timedelta ).

To get other time units, you could easily calculate them, or use time module, ie:

from time import strftime
from time import gmtime

strftime("%H:%M:%S", gmtime(td.total_seconds()))

where td is your timedelta object.
