用Python写一个俄罗斯方块游戏代码

当然可以！以下是一个俄罗斯方块游戏的Python代码：

import pygame
import random

# 设置窗口大小
screen_width = 320
screen_height = 480

# 初始化 Pygame
pygame.init()

# 创建窗口
screen = pygame.display.set_mode((screen_width, screen_height))

# 游戏标题
pygame.display.set_caption('俄罗斯方块')

# 颜色定义（RGB格式）
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
YELLOW = (255, 255, 0)

# 方块大小定义
block_size = 20

# 定义方块的形状
tetrominoes = [
    [[1, 1, 1],
     [0, 1, 0]],
    [[0, 2, 2],
     [2, 2, 0]],
    [[3, 3, 0],
     [0, 3, 3]],
    [[4, 0, 0],
     [4, 4, 4]],
    [[0, 0, 5],
     [5, 5, 5]],
    [[6, 6, 6, 6]],
    [[7, 7],
     [7, 7]],
]

# 定义方块的颜色
block_colors = [
    WHITE,
    YELLOW,
    BLUE,
    RED,
    GREEN,
    # PURPLE
    (255,0,255),
    # ORANGE
    (255,165,0)
]

# 获取一个新的方块
def new_block():
    block = random.choice(tetrominoes)
    color = random.choice(block_colors)
    return block, color

# 绘制方块
def draw_block(x, y, color):
    pygame.draw.rect(screen, color, (x * block_size, y * block_size, block_size, block_size))
    pygame.draw.rect(screen, BLACK, (x * block_size, y * block_size, block_size, block_size), 2)

# 检查方块是否合法
def check_piece_valid(piece, x, y):
    try:
        for row in range(len(piece)):
            for col in range(len(piece[0])):
                if piece[row][col] == 0:
                    continue
                if x + col < 0 or x + col >= screen_width // block_size:
                    return False
                if y + row < 0 or y + row >= screen_height // block_size:
                    return False
        return True
    except IndexError:
        return False

# 游戏循环
def game_loop():
    # 初始位置
    current_x, current_y = screen_width // block_size // 2, 0

    # 获取新的方块和颜色
    current_piece, current_color = new_block()
    
    while True:

        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                exit()
        
        # 检查是否可以下落
        if check_piece_valid(current_piece, current_x, current_y + 1):
            current_y += 1
        else:
            # 不再可以下落，将方块固定在当前位置
            for row in range(len(current_piece)):
                for col in range(len(current_piece[0])):
                    if current_piece[row][col] != 0:
                        draw_block(current_x + col, current_y + row, current_color)
          
            # 获取新的方块和颜色
            current_piece, current_color = new_block()
            current_x, current_y = screen_width // block_size // 2, 0
        
        # 绘制当前方块
        screen.fill(BLACK)
        for row in range(len(current_piece)):

                if current_piece[row][col] != 0:
                    draw_block(current_x + col, current_y + row, current_color)
        
        # 设置帧率
        pygame.display.set_caption('俄罗斯方块（帧率：' + str(int(clock.get_fps())) + '）')
        
        # 更新屏幕
        pygame.display.update()
        
        # 设置帧率
        clock.tick(25)

# 启动游戏
clock = pygame.time.Clock()
game_loop()
