Summing up set elements(HH:MM:SS)

[perfringo]

It depends what you want. if one wants whole timedelta in seconds then .total_seconds() should be used instead of .seconds:

add_time_2 = {"23:00:15", "6:15:15", "5:15:15"}

total = sum(map(convert, add_time_2), timedelta())

print(total)

# output -> 1 day, 10:30:45

print(total.total_seconds())

# output -> 124245.0 

time = total.total_seconds()

hours, reminder   = divmod(int(time), 3600)
minutes, seconds = divmod(reminder, 60)
print(f'the total time is {hours}:{minutes}:{seconds}')

# output -> the total time is 34:30:45
