That's correct! I just simply added an extra "false element". Once the city variable reaches it, the program shuts down. Here's the code I came up with which is super simple, and it works:

        city_array = ['1', '2', '3', '4']
        city = get_next_element(city_array)
        print(f"Assigned value: {city}")

        if city == '4':
            break
