俄罗斯方块python代码不带界面

下面是一个简单的俄罗斯方块的Python代码，不带界面：

import random

# 定义俄罗斯方块的方块形状
tetrominoes = [
    [[0, 1, 0],
     [1, 1, 1],
     [0, 0, 0]],
    [[1, 1],
     [1, 1]],
    [[1, 0, 0],
     [1, 1, 1],
     [0, 0, 0]],
    [[0, 0, 1],
     [1, 1, 1],
     [0, 0, 0]],
    [[1, 1, 0],
     [0, 1, 1],
     [0, 0, 0]],
    [[0, 1, 1],
     [1, 1, 0],
     [0, 0, 0]],
    [[1, 1, 1, 1]]
]

# 定义俄罗斯方块的初始位置和形状
current_tetromino = random.choice(tetrominoes)
current_position = {'x': 4, 'y': 0}

# 定义俄罗斯方块的游戏区域
game_area = [[0 for _ in range(10)] for _ in range(20)]

# 定义俄罗斯方块的函数
def draw_game_area():
    for row in game_area:
        print(row)

def check_collision():
    for i in range(len(current_tetromino)):
        for j in range(len(current_tetromino[i])):
            if current_tetromino[i][j] == 1:
                if current_position['x'] + j < 0 or current_position['x'] + j > 9 or current_position['y'] + i > 19 or game_area[current_position['y'] + i][current_position['x'] + j] != 0:
                    return True
    return False

def merge_tetromino():
    for i in range(len(current_tetromino)):
        for j in range(len(current_tetromino[i])):
            if current_tetromino[i][j] == 1:
                game_area[current_position['y'] + i][current_position['x'] + j] = 1

def check_lines():
    lines_to_remove = []
    for i in range(len(game_area)):
        if 0 not in game_area[i]:
            lines_to_remove.append(i)
    for line in lines_to_remove:
        game_area.pop(line)
        game_area.insert(0, [0 for _ in range(10)])

def new_tetromino():
    global current_tetromino, current_position
    current_tetromino = random.choice(tetrominoes)
    current_position = {'x': 4, 'y': 0}

# 运行俄罗斯方块游戏
while True:
    draw_game_area()
    user_input = input('Use left, right and down arrow keys to move the tetromino. Press q to quit.')
    if user_input == 'q':
        break
    elif user_input == 'left':
        current_position['x'] -= 1
        if check_collision():
            current_position['x'] += 1
    elif user_input == 'right':
        current_position['x'] += 1
        if check_collision():
            current_position['x'] -= 1
    elif user_input == 'down':
        current_position['y'] += 1
        if check_collision():
            current_position['y'] -= 1
            merge_tetromino()
            check_lines()
            new_tetromino()

该代码实现了一个简单的俄罗斯方块游戏，不带图形界面。玩家可以使用键盘上的箭头键来控制方块的移动，每当方块落到底部时，就会检查是否有行已满，如果有满行，则删除该行并向上移动所有行。游戏结束当玩家按下“q”键时。
