このコードを1つの関数に結合する方法はありますか？

Question

このコードは、オフィスの開閉時間を設定するために使用され、4つの機能は開閉時間を増減します。

This is how it looks on the dashboard

closehour = 17 
closeminute = 0 
openhour = 8 
openminute = 0 


def increaseOpenTimeScript(): 
    global openhour 
    global openminute 
    if openhour == 23 and openminute == 50: 
     openhour = 0 
     openminute = 0 
     time = "{}:{}0".format(openhour,openminute) 
    elif openminute == 50: 
     openminute = 0 
     openhour+=1 
     time = "{}:{}0".format(openhour, openminute) 
    else: 
     openminute+= 10 
     time = "{}:{}".format(openhour, openminute) 
    office.office1.officeOpenValue.config(text=time) 

これは、機能の一つである、開放時間を減少させる閉鎖時間を増加させると終了時間を減少させることのような3以上です。 変更を簡単にするために、このコードをすべて1つの関数に結合したいと思います。ここで

すべての機能です：

def decreaseOpenTimeScript(): 
    global openhour 
    global openminute 
    if openminute >= 10: 
     openminute -= 10 
     if openminute == 0: 
      time = "{}:{}0".format(openhour, openminute) 
     else: 
      time = "{}:{}".format(openhour,openminute) 
    elif openhour > 0 and openminute == 0: 
     openminute = 50 
     openhour -= 1 
     time = "{}:{}".format(openhour,openminute) 
    elif openhour == 0 and openminute == 0: 
     openhour = 23 
     openminute = 50 
     time = "{}:{}".format(openhour, openminute) 
    office.office1.officeOpenValue.config(text=time) 


def increaseCloseTimeScript(): 
    global closehour 
    global closeminute 
    if closehour == 23 and closeminute == 50: 
     closehour = 0 
     closeminute = 0 
     time = "{}:{}0".format(closehour,closeminute) 
    elif closeminute == 50: 
     closeminute = 0 
     closehour+=1 
     time = "{}:{}0".format(closehour,closeminute) 
    else: 
     closeminute+= 10 
     time = "{}:{}".format(closehour,closeminute) 
    office.office1.officeCloseValue.config(text=time) 


def decreaseCloseTimeScript(): 
    global closehour 
    global closeminute 
    if closeminute >= 10: 
     closeminute -= 10 
     if closeminute == 00: 
      time = "{}:{}0".format(closehour,closeminute) 
     else: 
      time = "{}:{}".format(closehour, closeminute) 
    elif closehour > 0 and closeminute == 0: 
     closehour-=1 
     closeminute = 50 
     time = "{}:{}".format(closehour,closeminute) 
    elif closehour == 0 and closeminute == 0: 
     closehour = 23 
     closeminute = 50 
     time = "{}:{}".format(closehour, closeminute) 
    office.office1.officeCloseValue.config(text=time) 

Answer 1

クラスを作成し、ちょうどそのクラスのメソッドを定義する方が簡単でしょうか？その後、各機能を実行するためにクラスを使用することができます。
