How can you go out of a function in python?

Question

How can you go out of a function in python??

Look at this program

For example:

import pygame, sys
from pygame.locals import *

pygame.init()

level = 0
x = 0

def eg_func():
    global x
    x = 10

def eg_func2():
    global x
    x = 2

while True:
    if level == 0:       
        eg_func()

    if playing == True:
        eg_func2()   

    print(x)

pygame.quit()
quit

So, how can I do that eg_func() stops but level keeps being 0 and not changing global -> because in my program I can't change it?

Thanks for everything, probably it's a simple thing.

You have to use global x to tell Python to change the value of the global x value, instead of defining a local x variable inside the function.

import pygame, sys
from pygame.locals import *

pygame.init()

level = 0
x = 0

def eg_func():
    global x
    x = 10

def eg_func2():
    x = 2

while True:
    if level == 0:       
        eg_func()

    if playing == True:
        eg_func2()   

    print(x)

pygame.quit()
quit
