change value of a variable without a function using a tkinter button

Question

I am new to programming and I want to know If there is any way to change the value of a variable with a Tkinter button out calling a function. As I have to give a function as command to change the value of any variable.

Like this:

import tkinter as tk

a = 1


def test():
    global a
    a = 2
    return


root = tk.Tk()

b = tk.Button(root, text="Click", command=test)
b.pack()

root.mainloop()

But I want to know if there is a way to do it directly without using any function.

Something that might look like this:

command = (a = 2)

nope, you have to use a function, but why don't you want to use it? — surftijmen

@TijmenThankyou Sir, For your quick response, I just wanted to know if it was possible as there is a chance of running into errors if one has to change the value of more than one variable. — DaniyalAhmadSE

@Tijmen No thanks, I just meant "There is a Chance" of running into errors. — DaniyalAhmadSE

You have to use a function, otherwise it won't work.
