Как можно сократить/оптимизировать эту функцию?

Только начал изучать Python, это часть моей первой программы, как можно сократить/оптимизировать эту часть кода? Функция работает с библиотекой tkinter и time.

def start():
global value1, value2, value3, RB
global exc1, exc2, exc3, exc4, exc5, exc6

while True:
    exc1 = value1 // 10 % 10
    exc2 = value1 % 10
    exc3 = value2 // 10 % 10
    exc4 = value2 % 10
    exc5 = value3 // 10 % 10
    exc6 = value3 % 10

    if value2 == 0 and value3 == 0 and value1 > value4:
        value1 = value1 - 1
        value2 = value2 + 59
        value3 = value3 + 60
    if value3 == 0 and value2 > value5:
        value2 = value2 - 1
        value3 = value3 + 60
