Subtract hours and minutes from time

In my task what I need to do is to subtract some hours and minutes like (0:20,1:10...any value) from time (2:34 PM) and on the output side I need to display the time after subtraction. time and hh:mm value are hardcoded

Ex:

my_time = 1:05 AM

duration = 0:50

so output should be 12:15 PM

Output should be exact and in AM/PM Format and Applicable for all values (0:00 < Duration > 6:00) .

I don't care about seconds, I only need the hours and minutes.

Solution 1:

from datetime import datetime, timedelta

d = datetime.today() - timedelta(hours=0, minutes=50)

d.strftime('%H:%M %p')

Solution 2:

This worked for me :

from datetime import datetime
s1 = '10:04:00'
s2 = '11:03:11' # for example
format = '%H:%M:%S'
time = datetime.strptime(s2, format) - datetime.strptime(s1, format)
print time
