python编写一个俄罗斯方块游戏

好的，以下是一个简单的俄罗斯方块游戏的 Python 代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 640
WINDOW_HEIGHT = 480

# 方块大小
BLOCK_SIZE = 20

# 游戏区域大小
GAME_AREA_WIDTH = 10
GAME_AREA_HEIGHT = 20

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GRAY = (128, 128, 128)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
YELLOW = (255, 255, 0)

# 定义方块形状
SHAPES = [
    [[1, 1, 1, 1]],
    [[1, 1], [1, 1]],
    [[0, 1, 1], [1, 1, 0]],
    [[1, 1, 0], [0, 1, 1]],
    [[1, 0, 0], [1, 1, 1]],
    [[0, 0, 1], [1, 1, 1]],
    [[1, 1, 1], [0, 1, 0]],
]

# 游戏区域
game_area = [[0] * GAME_AREA_WIDTH for _ in range(GAME_AREA_HEIGHT)]

# 随机生成一个方块
def new_block():
    shape = random.choice(SHAPES)
    x = random.randint(0, GAME_AREA_WIDTH - len(shape[0]))
    y = 0
    return shape, x, y

# 判断方块是否可以移动
def can_move(shape, x, y):
    for i in range(len(shape)):
        for j in range(len(shape[0])):
            if shape[i][j] == 1:
                if x + j < 0 or x + j >= GAME_AREA_WIDTH or y + i >= GAME_AREA_HEIGHT or game_area[y + i][x + j] == 1:
                    return False
    return True

# 将方块加入游戏区域
def add_block_to_game_area(shape, x, y):
    for i in range(len(shape)):
        for j in range(len(shape[0])):
            if shape[i][j] == 1:
                game_area[y + i][x + j] = 1

# 判断是否有一行已经填满
def check_full_row():
    for i in range(GAME_AREA_HEIGHT):
        if sum(game_area[i]) == GAME_AREA_WIDTH:
            return i
    return -1

# 移除已经填满的一行
def remove_full_row(row):
    del game_area[row]
    game_area.insert(0, [0] * GAME_AREA_WIDTH)

# 绘制游戏区域
def draw_game_area(screen):
    for i in range(GAME_AREA_HEIGHT):
        for j in range(GAME_AREA_WIDTH):
            if game_area[i][j] == 1:
                pygame.draw.rect(screen, GRAY, (j * BLOCK_SIZE, i * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
            pygame.draw.rect(screen, WHITE, (j * BLOCK_SIZE, i * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE), 1)

# 绘制方块
def draw_block(screen, shape, x, y, color):
    for i in range(len(shape)):
        for j in range(len(shape[0])):
            if shape[i][j] == 1:
                pygame.draw.rect(screen, color, ((x + j) * BLOCK_SIZE, (y + i) * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
                pygame.draw.rect(screen, WHITE, ((x + j) * BLOCK_SIZE, (y + i) * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE), 1)

# 绘制分数
def draw_score(screen, score):
    font = pygame.font.SysFont(None, 30)
    text = font.render("Score: " + str(score), True, WHITE)
    screen.blit(text, (WINDOW_WIDTH - 100, 10))

# 创建游戏窗口
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("Tetris")

# 游戏循环
clock = pygame.time.Clock()
score = 0
fall_speed = 1
fall_speed_counter = 0
block_shape, block_x, block_y = new_block()
game_over = False

while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT and can_move(block_shape, block_x - 1, block_y):
                block_x -= 1
            elif event.key == pygame.K_RIGHT and can_move(block_shape, block_x + 1, block_y):
                block_x += 1
            elif event.key == pygame.K_DOWN and can_move(block_shape, block_x, block_y + 1):
                block_y += 1
            elif event.key == pygame.K_SPACE:
                while can_move(block_shape, block_x, block_y + 1):
                    block_y += 1

    # 更新方块下落速度
    fall_speed_counter += 1
    if fall_speed_counter >= 60 // fall_speed:
        fall_speed_counter = 0
        if can_move(block_shape, block_x, block_y + 1):
            block_y += 1
        else:
            add_block_to_game_area(block_shape, block_x, block_y)
            full_row = check_full_row()
            while full_row != -1:
                remove_full_row(full_row)
                score += 10
                full_row = check_full_row()
            block_shape, block_x, block_y = new_block()
            if not can_move(block_shape, block_x, block_y):
                game_over = True

    # 绘制游戏界面
    screen.fill(BLACK)
    draw_game_area(screen)
    draw_block(screen, block_shape, block_x, block_y, RED)
    draw_score(screen, score)
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(60)

# 关闭 Pygame
pygame.quit()

这个示例使用 Pygame 库来实现游戏界面和交互，实现了简单的俄罗斯方块游戏逻辑。你可以根据自己的需求对代码进行修改和扩展。
