基于python开发的俄罗斯方块

要使用Python开发俄罗斯方块，可以使用Pygame库，它是一个跨平台的Python游戏开发库。以下是一个简单的实现：

import pygame
import random

# 初始化 pygame
pygame.init()

# 游戏区域大小
WIDTH, HEIGHT = 300, 600
# 方块大小
BLOCK_SIZE = 30

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

# 方块形状和颜色
SHAPES = [
    [[1, 1], [1, 1]],  # 方块
    [[2, 2, 2], [0, 2, 0]],  # 闪电
    [[0, 3, 3], [3, 3, 0]],  # 反闪电
    [[4, 0, 0], [4, 4, 4]],  # 棒状
    [[0, 5, 0], [5, 5, 5]],  # T形
    [[6, 6, 0], [0, 6, 6]],  # 反Z形
    [[0, 7, 7], [7, 7, 0]]  # Z形
]
COLORS = [RED, GREEN, BLUE, WHITE, BLACK, (255, 128, 0), (128, 0, 255)]

# 创建游戏区域
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("俄罗斯方块")

# 创建字体
font = pygame.font.Font(None, 30)

# 随机选择一个形状和颜色
current_shape = random.choice(SHAPES)
current_color = random.choice(COLORS)

# 方块初始位置和速度
x, y = 120, 0
speed = 30

# 记录已经落下的方块
blocks = []

# 游戏主循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    # 检查方块是否碰到底部或已经落下的方块
    for i in range(len(current_shape)):
        for j in range(len(current_shape[i])):
            if current_shape[i][j] and (y + i + 1) * BLOCK_SIZE >= HEIGHT:
                blocks.append((x + j, y + i, current_color))
                current_shape = random.choice(SHAPES)
                current_color = random.choice(COLORS)
                x, y = 120, 0
                break
            elif current_shape[i][j] and (x + j, y + i + 1) in [(int(b[0]), int(b[1])) for b in blocks]:
                blocks.append((x + j, y + i, current_color))
                current_shape = random.choice(SHAPES)
                current_color = random.choice(COLORS)
                x, y = 120, 0
                break

    # 检查是否有满行
    full_rows = []
    for i in range(HEIGHT // BLOCK_SIZE):
        row = [(int(b[0]), int(b[1])) for b in blocks if int(b[1]) == i]
        if len(row) == WIDTH // BLOCK_SIZE:
            full_rows.append(i)
    for row in full_rows:
        blocks = [(b[0], b[1] + 1, b[2]) if b[1] < row else b for b in blocks]

    # 移动方块
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and x > 0:
        x -= BLOCK_SIZE
    if keys[pygame.K_RIGHT] and x < WIDTH - BLOCK_SIZE * len(current_shape[0]):
        x += BLOCK_SIZE
    if keys[pygame.K_DOWN]:
        speed = 100
    else:
        speed = 30
    if keys[pygame.K_SPACE]:
        current_shape = [[current_shape[j][i] for j in range(len(current_shape))] for i in range(len(current_shape[0]))]

    # 更新方块位置
    y += speed / 30
    screen.fill(BLACK)
    for i in range(len(current_shape)):
        for j in range(len(current_shape[i])):
            if current_shape[i][j]:
                pygame.draw.rect(screen, current_color, (x + j * BLOCK_SIZE, y + i * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
    for b in blocks:
        pygame.draw.rect(screen, b[2], (b[0] * BLOCK_SIZE, b[1] * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
    # 绘制当前得分
    score = len(blocks) // (WIDTH // BLOCK_SIZE)
    text = font.render("Score: " + str(score), True, WHITE)
    screen.blit(text, (10, 10))
    pygame.display.update()
    pygame.time.wait(100)

上述代码基于Pygame库，通过随机选择方块形状和颜色，处理键盘事件，记录已经落下的方块等，实现了一个简单的俄罗斯方块游戏。
