用 python 写一个 2048 游戏

好的，以下是一个简单的 Python 2048 游戏实现：

import random

# 初始化游戏棋盘
def init_board():
    board = [[0 for i in range(4)] for j in range(4)]
    return board

# 在棋盘上随机生成一个数
def generate_number(board):
    empty_cells = [(i, j) for i in range(4) for j in range(4) if board[i][j] == 0]
    if empty_cells:
        row, col = random.choice(empty_cells)
        board[row][col] = 2 if random.random() < 0.9 else 4
    return board

# 打印游戏棋盘
def print_board(board):
    for row in board:
        print(row)

# 检查游戏是否结束
def is_game_over(board):
    for row in board:
        if 0 in row:
            return False
    for i in range(4):
        for j in range(3):
            if board[i][j] == board[i][j+1] or board[j][i] == board[j+1][i]:
                return False
    return True

# 向左移动
def move_left(board):
    for row in board:
        new_row = [n for n in row if n != 0]
        new_row += [0] * (4 - len(new_row))
        for i in range(3):
            if new_row[i] == new_row[i+1] and new_row[i] != 0:
                new_row[i] *= 2
                new_row[i+1] = 0
        new_row = [n for n in new_row if n != 0]
        new_row += [0] * (4 - len(new_row))
        row[:] = new_row
    return board

# 向右移动
def move_right(board):
    for row in board:
        new_row = [n for n in row if n != 0]
        new_row = [0] * (4 - len(new_row)) + new_row
        for i in range(3, 0, -1):
            if new_row[i] == new_row[i-1] and new_row[i] != 0:
                new_row[i] *= 2
                new_row[i-1] = 0
        new_row = [n for n in new_row if n != 0]
        new_row = [0] * (4 - len(new_row)) + new_row
        row[:] = new_row
    return board

# 向上移动
def move_up(board):
    for i in range(4):
        col = [board[j][i] for j in range(4)]
        new_col = [n for n in col if n != 0]
        new_col += [0] * (4 - len(new_col))
        for j in range(3):
            if new_col[j] == new_col[j+1] and new_col[j] != 0:
                new_col[j] *= 2
                new_col[j+1] = 0
        new_col = [n for n in new_col if n != 0]
        new_col += [0] * (4 - len(new_col))
        for j in range(4):
            board[j][i] = new_col[j]
    return board

# 向下移动
def move_down(board):
    for i in range(4):
        col = [board[j][i] for j in range(4)]
        new_col = [n for n in col if n != 0]
        new_col = [0] * (4 - len(new_col)) + new_col
        for j in range(3, 0, -1):
            if new_col[j] == new_col[j-1] and new_col[j] != 0:
                new_col[j] *= 2
                new_col[j-1] = 0
        new_col = [n for n in new_col if n != 0]
        new_col = [0] * (4 - len(new_col)) + new_col
        for j in range(4):
            board[j][i] = new_col[j]
    return board

# 游戏主函数
def main():
    board = init_board()
    board = generate_number(board)
    board = generate_number(board)
    print_board(board)
    while not is_game_over(board):
        move = input("Enter move (left, right, up, down): ")
        if move == "left":
            board = move_left(board)
        elif move == "right":
            board = move_right(board)
        elif move == "up":
            board = move_up(board)
        elif move == "down":
            board = move_down(board)
        else:
            print("Invalid move")
            continue
        board = generate_number(board)
        print_board(board)
    print("Game over")

if __name__ == "__main__":
    main()

这个实现可能不是非常完善，但可以作为一个简单的 2048 游戏的基础。
