Sum up Time difference

[tester_V]

You guys did your best, I'm sure it all makes sens but not for my level of understanding..
Sorry about that!
I do not see how I can get from this:

 START TIME = 4/3/2023 4:18:57 PM
 END TIME = 4/3/2023 4:20:02 PM
 Time Difference  = 0:01:05-<class 'datetime.timedelta'>
 START TIME = 4/3/2023 4:24:06 PM
 END TIME = 4/3/2023 4:25:08 PM
 Time Difference  = 0:01:02-<class 'datetime.timedelta'>

to this:

deltas = [timedelta(hours=1, minutes=35, seconds=42) for _ in range(10)]
 
print(sum(deltas, timedelta(seconds=0)))

or to this:

x = timedelta(days=1), timedelta(days=1)
total = sum(a.total_seconds() for a in x)
print(total)

this is complicated... And I really appreciate your help!

Thank you guys, you are the best, I'll get it someday.
