Change variable value during a while loop?

[penahuse]

Hi!

Is there a way to hange variable value during a while loop?

example:

import win32api

global x
x = 1

if win32api.GetAsyncKeyState(0x70):
    x = 4

def lmb_down():
    lmb_state = win32api.GetKeyState(0x01)    
    return lmb_state < 0

while lmb_down():
    move_mouse x

So is possible change the value of x during the while loop? I mean if I press F1 while im pressing left mouse button and my mouse is moving 1 can it move 4?

Thanks
