Python编写2048

好的，下面是Python实现2048的代码示例：

import random

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

# 打印游戏面板
def print_board(board):
    for i in range(len(board)):
        for j in range(len(board)):
            print(board[i][j], end='\t')
        print()

# 在随机位置生成一个新数字
def generate_number(board):
    x = random.randint(0, len(board) - 1)
    y = random.randint(0, len(board) - 1)
    while board[x][y] != 0:
        x = random.randint(0, len(board) - 1)
        y = random.randint(0, len(board) - 1)
    board[x][y] = 2

# 向左移动
def move_left(board):
    for i in range(len(board)):
        j = 0
        while j < len(board) - 1:
            if board[i][j] == 0:
                k = j + 1
                while k < len(board) and board[i][k] == 0:
                    k += 1
                if k < len(board):
                    board[i][j] = board[i][k]
                    board[i][k] = 0
            if j < len(board) - 1 and board[i][j] == board[i][j + 1]:
                board[i][j] *= 2
                board[i][j + 1] = 0
                move_left(board)
            j += 1

# 向右移动
def move_right(board):
    for i in range(len(board)):
        j = len(board) - 1
        while j > 0:
            if board[i][j] == 0:
                k = j - 1
                while k >= 0 and board[i][k] == 0:
                    k -= 1
                if k >= 0:
                    board[i][j] = board[i][k]
                    board[i][k] = 0
            if j > 0 and board[i][j] == board[i][j - 1]:
                board[i][j] *= 2
                board[i][j - 1] = 0
                move_right(board)
            j -= 1

# 向上移动
def move_up(board):
    for j in range(len(board)):
        i = 0
        while i < len(board) - 1:
            if board[i][j] == 0:
                k = i + 1
                while k < len(board) and board[k][j] == 0:
                    k += 1
                if k < len(board):
                    board[i][j] = board[k][j]
                    board[k][j] = 0
            if i < len(board) - 1 and board[i][j] == board[i + 1][j]:
                board[i][j] *= 2
                board[i+1][j] = 0
                move_up(board)
            i += 1

# 向下移动
def move_down(board):
    for j in range(len(board)):
        i = len(board) - 1
        while i > 0:
            if board[i][j] == 0:
                k = i - 1
                while k >= 0 and board[k][j] == 0:
                    k -= 1
                if k >= 0:
                    board[i][j] = board[k][j]
                    board[k][j] = 0
            if i > 0 and board[i][j] == board[i - 1][j]:
                board[i][j] *= 2
                board[i - 1][j] = 0
                move_down(board)
            i -= 1

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

# 游戏主函数
def game():
    n = 4
    board = init_board(n)
    generate_number(board)
    generate_number(board)
    print_board(board)
    while not is_over(board):
        direction = input("请输入方向（w：上，s：下，a：左，d：右）：")
        if direction == 'a':
            move_left(board)
        elif direction == 'd':
            move_right(board)
        elif direction == 'w':
            move_up(board)
        elif direction == 's':
            move_down(board)
        else:
            print("输入有误，请重新输入！")
            continue
        generate_number(board)
        print_board(board)
    print("游戏结束！")

# 运行游戏
game()

这个代码实现了2048游戏的基本功能，可以通过控制台输入方向来移动方块，当所有方块被填满且无法再合并时，游戏结束。你可以根据需要对代码进行修改和优化。
