我已经创建了一个基本游戏。现在，我想扩展基本游戏并向其中添加视频游戏菜单。我有两个程序：
我想将两种代码集成为一个，以便我的游戏更具功能性。我只是一个初学者，需要有关如何操作的指导。感谢您的帮助。

创建游戏时，您需要一个名为The MainLoop的东西。每个循环中需要更新的所有代码都在此循环内。该循环永远运行直到游戏终止。选中这些video tutorials和this
让我给你举个例子：
import pygame
#Import literals such as QUIT
from pygame.locals import *
pygame.init()
w = 800
h = 600
screen = pygame.display.set_mode((w,h))
running = True
def MenuCode():
pass
def GameCode():
pass
#This is the Game Loop.
while running:
#Events are used to check if a key has
#been pressed or a mouse button or a mouse movement.
for event in pygame.event.get():
#If the user pressed the x button.
#terminate the while loop.
if event.type == QUIT:
running = False
break;
#In every frame you must clean the window with a color
#in order to draw anythin else above it.
screen.fill((0,0,0))
#Here draw anything you like
#Also somewhere here call all the code that needs to be
#called every frame (Menu code, Game code, etc)
MenuCode()
GameCode()
#Lastly you must update the display.
#The most important thing that this does
#is called buffer swapping, check it out.
pygame.display.update()
#When the loop terminates, terminate pygame.
pygame.quit()
