### Python实现俄罗斯方块示例代码 以下是一个使用Python标准库（如`os`, `datetime`, `random`）和图形界面库`Tkinter`的俄罗斯方块示例代码。此代码还结合了文件读写功能，用于保存和加载游戏分数[^1]。 ```python import tkinter as tk from tkinter import messagebox import random import os import datetime # 定义俄罗斯方块的基本参数 BLOCK_SIZE = 30 WIDTH = 10 HEIGHT = 20 SCORE_FILE = "tetris_scores.txt" # 定义方块形状 SHAPES = [ [[1, 1, 1, 1]], [[1, 1], [1, 1]], [[1, 1, 0], [0, 1, 1]], [[0, 1, 1], [1, 1, 0]], [[1, 1, 1], [0, 1, 0]] ] # 定义颜色 COLORS = ['red', 'blue', 'green', 'yellow', 'purple'] class Tetris: def __init__(self, master): self.master = master self.canvas = tk.Canvas(master, width=WIDTH * BLOCK_SIZE, height=HEIGHT * BLOCK_SIZE) self.canvas.pack() self.score = 0 self.level = 1 self.lines_cleared = 0 self.grid = [[0 for _ in range(WIDTH)] for _ in range(HEIGHT)] self.current_shape = None self.game_over = False self.init_game() self.bind_keys() def init_game(self): self.new_shape() self.draw_grid() self.update_score() def bind_keys(self): self.master.bind("<Left>", lambda _: self.move(-1)) self.master.bind("<Right>", lambda _: self.move(1)) self.master.bind("<Down>", lambda _: self.drop()) self.master.bind("<Up>", lambda _: self.rotate()) def new_shape(self): shape = random.choice(SHAPES) color = random.choice(COLORS) self.current_shape = { 'x': WIDTH // 2 - len(shape[0]) // 2, 'y': 0, 'shape': shape, 'color': color } def draw_grid(self): self.canvas.delete("all") for y, row in enumerate(self.grid): for x, val in enumerate(row): if val: self.draw_block(x, y, COLORS[val - 1]) if self.current_shape: for y, row in enumerate(self.current_shape['shape']): for x, val in enumerate(row): if val: self.draw_block( self.current_shape['x'] + x, self.current_shape['y'] + y, self.current_shape['color'] ) def draw_block(self, x, y, color): self.canvas.create_rectangle( x * BLOCK_SIZE, y * BLOCK_SIZE, (x + 1) * BLOCK_SIZE, (y + 1) * BLOCK_SIZE, fill=color, outline="black" ) def move(self, dx): if not self.game_over: self.current_shape['x'] += dx if not self.valid_position(): self.current_shape['x'] -= dx self.draw_grid() def drop(self): if not self.game_over: self.current_shape['y'] += 1 if not self.valid_position(): self.current_shape['y'] -= 1 self.freeze_shape() self.clear_lines() self.new_shape() if not self.valid_position(): self.game_over = True self.save_score() messagebox.showinfo("Game Over", f"Final Score: {self.score}") self.draw_grid() def rotate(self): if not self.game_over: rotated = list(zip(*reversed(self.current_shape['shape']))) old_shape = self.current_shape['shape'] self.current_shape['shape'] = rotated if not self.valid_position(): self.current_shape['shape'] = old_shape self.draw_grid() def valid_position(self): for y, row in enumerate(self.current_shape['shape']): for x, val in enumerate(row): if val: nx, ny = self.current_shape['x'] + x, self.current_shape['y'] + y if nx < 0 or nx >= WIDTH or ny < 0 or ny >= HEIGHT or self.grid[ny][nx]: return False return True def freeze_shape(self): for y, row in enumerate(self.current_shape['shape']): for x, val in enumerate(row): if val: nx, ny = self.current_shape['x'] + x, self.current_shape['y'] + y self.grid[ny][nx] = COLORS.index(self.current_shape['color']) + 1 def clear_lines(self): lines_cleared = 0 for y, row in enumerate(self.grid): if all(row): lines_cleared += 1 del self.grid[y] self.grid.insert(0, [0 for _ in range(WIDTH)]) if lines_cleared: self.score += lines_cleared * 100 self.lines_cleared += lines_cleared self.update_score() def update_score(self): score_label.config(text=f"Score: {self.score}") def save_score(self): with open(SCORE_FILE, 'a') as f: timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S") f.write(f"{timestamp} - Score: {self.score}\n") if __name__ == "__main__": root = tk.Tk() root.title("Tetris Game") score_label = tk.Label(root, text="Score: 0") score_label.pack() game = Tetris(root) while not game.game_over: root.after(500, game.drop) root.mainloop() ``` 上述代码实现了基本的俄罗斯方块逻辑，包括方块生成、移动、旋转、消除行等功能。同时，通过`save_score`函数将玩家的得分保存到文件中，并在程序退出时记录时间戳。
