python写个俄罗斯方块游戏

好的，下面是一个简单的 Python 俄罗斯方块游戏的代码示例：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口大小
WIDTH = 800
HEIGHT = 600
SCREEN = pygame.display.set_mode((WIDTH, HEIGHT))

# 定义游戏颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

# 设置游戏字体
FONT = pygame.font.SysFont(None, 50)

# 定义方块大小和行列数
BLOCK_SIZE = 30
ROWS = HEIGHT // BLOCK_SIZE
COLS = WIDTH // BLOCK_SIZE

# 定义方块类
class Block:
    def __init__(self, x, y, color):
        self.x = x
        self.y = y
        self.color = color

    def draw(self):
        pygame.draw.rect(SCREEN, self.color, (self.x * BLOCK_SIZE, self.y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

# 定义俄罗斯方块类
class Tetromino:
    def __init__(self):
        self.x = COLS // 2
        self.y = 0
        self.color = random.choice([RED, GREEN, BLUE])
        self.blocks = []

        self.shapes = [
            [(0, 0), (1, 0), (2, 0), (3, 0)],   # I
            [(0, 0), (1, 0), (0, 1), (1, 1)],   # O
            [(0, 0), (1, 0), (2, 0), (2, 1)],   # L
            [(0, 0), (1, 0), (2, 0), (0, 1)],   # J
            [(1, 0), (2, 0), (0, 1), (1, 1)],   # S
            [(0, 0), (1, 0), (1, 1), (2, 1)],   # Z

        ]

            block = Block(self.x + pos[0], self.y + pos[1], self.color)
            self.blocks.append(block)

    def move_down(self):
        for block in self.blocks:
            block.y += 1
        self.y += 1

    def move_left(self):
        if self.x > 0:
            for block in self.blocks:
                block.x -= 1
            self.x -= 1

    def move_right(self):
        if self.x < COLS - max(pos[0] for pos in self.shape):
            for block in self.blocks:
                block.x += 1
            self.x += 1

    def rotate(self):
        if self.shape != self.shapes[1]:
            new_shape = []
            for pos in self.shape:
                new_pos = (-pos[1], pos[0])
                new_shape.append(new_pos)

            min_x = min(pos[0] for pos in new_shape)
            delta_x = self.x - (max_x + min_x) // 2
            self.shape = new_shape
            for i, block in enumerate(self.blocks):
                block.x = self.x + self.shape[i][0] + delta_x
                block.y = self.y + self.shape[i][1]

    def draw(self):
        for block in self.blocks:
            block.draw()

# 定义游戏主循环
def main():

                if y >= 0:
                    grid[y][x] = block

            tetromino = Tetromino()

        for y in range(ROWS):

        tetromino.draw()

        score_text = FONT.render("Score: " + str(score), True, WHITE)
        SCREEN.blit(score_text, (10, 10))

        pygame.display.update()
        clock.tick(60)

# 启动游戏
if __name__ == "__main__":
    grid = [[None for _ in range(COLS)] for _ in range(ROWS)]
    main()

这是一个基本的俄罗斯方块游戏，你可以根据自己的需要进行修改和扩展。
