[FIXED] NameError variable n undefined

Issue

I am actually doing a program with tkinter. I am trying to do a window log, like windows when you transfer a big directory. I am desperately trying to do that every second a string of my list is printed on the text page. and it says NameError: name 'n' is not defined but I have used the global method, so normally it should work...

here's my code:

n = 0

def refresh():
    global n
    write(thingstotestlist[int(n)])
    n = n + 1
    if n > len(thingstotestlist):
        return

    textbox.after(1000, refresh)

textbox.after(random.randint(500, 1000), refresh)

please help me

Solution

Move your global statement above as so:

global n
n = 0

def refresh():
global n
...
