我浏览了这个网站，但我找不到一个问题，可以帮助我了解如何在我的计算器代码中输入一个班次按钮。你能帮忙吗？
from tkinter import*
mode = 0
def ShiftUse(mode):
?????????
text_Input.set(mode)
return
def btnUse(numbers):
global operator
operator=operator + str(numbers)
text_Input.set(operator)
def btnClearUse():
global operator
operator=''
text_Input.set('')
def btnEaqualsUse():
global operator
sumup=str(eval(operator))
text_Input.set(sumup)
operator=''

calc.title('Calculator')

我创建了这个功能和按钮，我根本不知道如何让按钮将所有其他值切换到我选择的其他值。这可能是显而易见的，当我得到答案时我可能会踢自己，但我仍然会帮助你。
