Can someone help me with my code

Question

ive been working on a little program using python and tkinter, everytime i click the button its supposed to raise the number then print it in the console. The program runs, but when i click the button it gives me an error saying "local variable 'x' referenced before assignment"

here is my code:

from tkinter import *
root = Tk()
x = 5

def printName(event):
print(x)
x += 1

object_printButton = Button(root, text='Print something')
object_printButton.bind('<Button-1>', printName)
object_printButton.pack()
root.mainloop()

Answer 1

Python automatically reads global variables as if they are in the function scope, but it will not reach out to the global context on *writes* unless you deliberately indicate you want the global variable first:

x = 5

def test():
global x
x += 1

test()

edit: here's a ref with some discussion of how Python resolves variables, etc:
