Im trying to get a return value from a function I have. I am getting the value but it is running through the function again and then getting the value even though i just want the value.

import pygame

def create_input_window():
    pygame.init()
    screen_width = 400
    screen_height = 150
    screen = pygame.display.set_mode((screen_width, screen_height))
    pygame.display.set_caption("Input Window")
    
    input_font = pygame.font.Font(None, 32)
    input_text = ""
    city_input = ""
    input_active = True
    city_entered = False

    while input_active:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                return None, None

            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RETURN:
                    if not city_entered:
                        city_entered = True
                    else:
                        input_active = False
                elif event.key == pygame.K_BACKSPACE:
                    if not city_entered:
                        input_text = input_text[:-1]
                    else:
                        city_input = city_input[:-1]
                else:
                    if not city_entered:
                        input_text += event.unicode
                    else:
                        city_input += event.unicode

        screen.fill((255, 255, 255))  # Clear the screen
        pygame.draw.rect(screen, (0, 0, 0), (50, 10, 300, 50), 2)  # Draw input box for input_text
        pygame.draw.rect(screen, (0, 0, 0), (50, 70, 300, 50), 2)  # Draw input box for city_input

        text_surface = input_font.render(input_text, True, (0, 0, 0))
        screen.blit(text_surface, (55, 15))  # Display input_text

        text_surface = input_font.render(city_input, True, (0, 0, 0))
        screen.blit(text_surface, (55, 75))  # Display city_input

        pygame.display.update()

    with open("input.txt", "w") as file:
        file.write(input_text)

    return str(city_input)

def get_city_input():
    city_input = create_input_window()
    return city_input


def main():
    while True:
        city_input = get_city_input()
        print("City name:", city_input)
if __name__ == "__main__":
    main()

I tried using a global variable instead of the function to get the variable but i dont know if i did it correctly. I asked chatgpt and got this which is similar to what I tried. I also am not too familiar with python and how it works.
import pygame

Global variable to store the city input

city_input = “”

global city_input # Access the global city_input variable

pygame.display.set_caption(“Input Window”)

input_font = pygame.font.Font(None, 32)
input_text = ""
input_active = True
city_entered = False

while input_active:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            return None

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RETURN:
                if not city_entered:
                    city_entered = True
                else:
