写一篇基于python语言的2048游戏的代码

好的，以下是基于Python语言的2048游戏代码：

import random

# 初始化游戏面板
def init_board():
    board = [[0] * 4 for i in range(4)]
    return board

# 在游戏面板中随机生成一个新的数字方块
def new_block(board):
    empty_cells = []
    for i in range(4):
        for j in range(4):
            if board[i][j] == 0:
                empty_cells.append((i, j))
    if len(empty_cells) > 0:
        row, col = random.choice(empty_cells)
        board[row][col] = random.choice([2, 4])

# 在游戏面板中移动数字方块
def move(board, direction):
    if direction == "left":
        for i in range(4):
            board[i] = merge(board[i])
    elif direction == "right":
        for i in range(4):
            board[i] = merge(board[i][::-1])[::-1]
    elif direction == "up":
        for i in range(4):
            col = [board[j][i] for j in range(4)]
            merged_col = merge(col)
            for j in range(4):
                board[j][i] = merged_col[j]
    elif direction == "down":
        for i in range(4):
            col = [board[j][i] for j in range(4)][::-1]
            merged_col = merge(col)[::-1]
            for j in range(4):
                board[j][i] = merged_col[j]

# 合并数字方块
def merge(cells):
    merged_cells = [0] * 4
    j = 0
    for i in range(4):
        if cells[i] != 0:
            if merged_cells[j] == 0:
                merged_cells[j] = cells[i]
            elif merged_cells[j] == cells[i]:
                merged_cells[j] *= 2
                j += 1
            else:
                j += 1
                merged_cells[j] = cells[i]
    return merged_cells

# 判断游戏是否结束
def is_over(board):
    for i in range(4):
        for j in range(4):
            if board[i][j] == 0:
                return False
            if i < 3 and board[i][j] == board[i+1][j]:
                return False
            if j < 3 and board[i][j] == board[i][j+1]:
                return False
    return True

# 打印游戏面板
def print_board(board):
    for i in range(4):
        for j in range(4):
            print(board[i][j], end="\t")
        print()

# 主函数
def main():
    board = init_board()
    new_block(board)
    new_block(board)
    print_board(board)
    while not is_over(board):
        direction = input("Enter direction: ")
        move(board, direction)
        new_block(board)
        print_board(board)
    print("Game over")

if __name__ == "__main__":
    main()

这个代码实现了一个基本的2048游戏，可以通过输入left、right、up、down来移动数字方块，每移动一次会随机生成一个新的数字方块，直到游戏结束。
