Summing up set elements(HH:MM:SS)

[Pedroski55]

Hope perfingo doesn't mind me infringing on his excellent function.

I was interested to see what happens when hour > 23 or time > 23:59:59

from datetime import timedelta

add_time = {"23:00:15", "6:15:15", "5:15:15"}
 
def convert(time_str):
    hrs, mins, secs = (int(unit) for unit in time_str.split(':'))
    return timedelta(hours=hrs, minutes=mins, seconds=secs)
 
total = sum(map(convert, add_time), timedelta())
minute  = 60
hour    = minute * 60
seconds = total.seconds
hours   = divmod(seconds, hour)
minutes = divmod(hours[1], minute)
rem_seconds = minutes[1]
print(f'the total time is {hours[0]}:{minutes[0]}:{minutes[1]}')

Sure enough, looks like you won't get more than 23 hours!
