Формат даты и времени более 24 часов

Я пытаюсь добавить время и получить результат как hh:mm:ss, но когда datetime превышает 24 часа, он становится x Days, hh:mm:ss. Есть ли способ иметь только hh:mm:ss дольше 24 часов?

import datetime
from datetime import timedelta

print("Welcome to TimeCalc")

print("Calculating Durations")

clear = True
while clear == True:
    # first input
    firstNumber = True
    while firstNumber == True:
        time_1 = input("Please enter a time [hh:mm:ss] including 0s: ")
        if len(time_1) > 0 and len(time_1) >= 8 and time_1[-6] == ":" and time_1[-3] == ":" and int(time_1[-5:-3]) < 60 and int(time_1[-2:]) < 60:
            hours_1 = time_1[:-6]
            minutes_1 = time_1[-5:-3]
            seconds_1 = time_1[-2:]
            hours_1 = int(hours_1)
            minutes_1 = int(minutes_1)
            seconds_1 = int(seconds_1)
            firstNumber = False
        else:
            print("Invalid Syntax")
    time_1 = datetime.timedelta(hours=hours_1, minutes=minutes_1, seconds=seconds_1)

    cont = True
    while cont == True:
        # second input
        secondNumber = True
        while secondNumber == True:
            time_2 = input("Please enter a time to add [hh:mm:ss] including 0s: ")
            if len(time_2) > 0 and len(time_2) >= 8 and time_2[-6] == ":" and time_2[-3] == ":" and int(time_2[-5:-3]) < 60 and int(time_2[-2:]) < 60:
                hours_2 = time_2[:-6]
                minutes_2 = time_2[-5:-3]
                seconds_2 = time_2[-2:]

                seconds_2 = int(seconds_2)
                secondNumber = False
            else:
                print("Invalid Syntax")
        time_2 = datetime.timedelta(hours = hours_2, minutes = minutes_2, seconds = seconds_2)

        total = time_1 + time_2
        print("The total duration is: " + str(total))

        # continue, clear, or exit
        choice = input("Continue: Y | Clear: N | Exit: X: ")
        if choice == "Y" or choice == "y":
            time_1 = total
        elif choice == "N" or choice == "n":
            cont = False
        elif choice == "X" or choice == "x":
            quit()
