要实现超级玛丽游戏，你需要先安装pygame库。你可以使用以下命令在命令行中安装：

pip install pygame

接下来，创建一个名为mario.py的文件，并在其中编写以下代码：
```python
import pygame
import sys
from pygame.locals import *

初始化pygame

pygame.init()

设置屏幕大小和标题

screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption(‘超级玛丽’)

加载游戏背景和角色图像

background_image = pygame.image.load(‘background.png’)
mario_image = pygame.image.load(‘mario.png’)

定义游戏常量

MARIO_SPEED = 5
GRAVITY = 0.5
JUMP_BOOST = 7

初始化游戏角色和位置

mario_x = screen_width // 2 - MARIO_SPEED // 2
mario_y = screen_height - MARIO_SPEED - 20
mario_rect = pygame.Rect(mario_x, mario_y, MARIO_SPEED, MARIO_SPEED)

定义游戏循环和帧率控制

clock = pygame.time.Clock()
running = True
while running:
for event in pygame.event.get():
if event.type == QUIT:
running = False
elif event.type == KEYDOWN:
if event.key == K_SPACE:
mario_y -= JUMP_BOOST
elif event.type == KEYUP:
if event.key == K_SPACE:
mario_y += GRAVITY
keys = pygame.key.get_pressed()
if keys[K_LEFT]:
mario_x -= MARIO_SPEED
mario_rect = pygame.Rect(mario_x, mario_y, MARIO_SPEED, MARIO_SPEED)
if keys[K_RIGHT]:
mario_x += MARIO_SPEED
mario_rect = pygame.Rect(mario_x, mario_y, MARIO_SPEED, MARIO_SPEED)
if keys[K_UP]:
if mario_y > MARIO_SPEED:
mario_y -= JUMP_BOOST - GRAVITY * 2
else:
mario_y = screen_height - MARIO_SPEED - 20
screen.blit(background_image, (0, 0))
screen.blit(mario_image, (mario_x, mario_y))
pygame.display.flip()
clock.tick(60)
pygame.quit()
