如何制作可选的 tkinter GUI？

Question

我有一个 tkinter GUI 代码，它执行映射到不同按钮/小部件的不同功能，我想为用户提供选择打开 GUI 窗口或直接从命令行执行的选项。

我尝试将 mainloop() 保留在可选开关内，例如：

if gui == "1":
    root.mainloop()
else:
    #command mode
    # call required functions here using user switches.

这是执行此操作的正确方法吗？当我在linux系统中尝试时，这是有效的。

Answer 1

root = Tk()
root.title('ATM v.keypad buttons //////dont acc work///////')
            
        

# creates the buttons adds no value tho

# size of button
gridlabel1 = Button(root, text='1', padx=50, pady=50)
gridlabel2 = Button(root, text='2', padx=50, pady=50)
gridlabel3 = Button(root, text='3', padx=50, pady=50)
gridlabel4 = Button(root, text='4', padx=50, pady=50)
gridlabel5 = Button(root, text='5', padx=50, pady=50)
gridlabel6 = Button(root, text='6', padx=50, pady=50)
gridlabel7 = Button(root, text='7', padx=50, pady=50)
gridlabel8 = Button(root, text='8', padx=50, pady=50)
gridlabel9 = Button(root, text='9', padx=50, pady=50)
gridlabel0 = Button(root, text='0', padx=50, pady=50)
cancelbutton = Button(root, text='cancel', padx=75, pady=50)
clearbutton = Button(root, text='clear', padx=75, pady=50)
enterbutton = Button(root, text='enter', padx=75, pady=50)
# prints the button at set location
gridlabel1.grid(row=0, column=0)
gridlabel2.grid(row=0, column=1)
gridlabel3.grid(row=0, column=2)
gridlabel4.grid(row=1, column=0)
gridlabel5.grid(row=1, column=1)
gridlabel6.grid(row=1, column=2)
gridlabel7.grid(row=2, column=0)
gridlabel8.grid(row=2, column=1)
gridlabel9.grid(row=2, column=2)
gridlabel0.grid(row=3, column=1)
cancelbutton.grid(row=0, column=4)
clearbutton.grid(row=1, column=4)
enterbutton.grid(row=2, column=4)
root.mainloop()

这是我的示例，请注意我如何将 root.mainloop() 放在最后
缩进，因为它在 if 语句中
