Python编写2048游戏并显示分数

以下是Python编写的2048游戏和显示分数的示例代码：

import random

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

# 在随机位置生成2或4
def generate_num(board):
    empty_pos = []
    for i in range(4):
        for j in range(4):
            if board[i][j] == 0:
                empty_pos.append((i, j))
    if not empty_pos:
        return False
    x, y = random.choice(empty_pos)
    board[x][y] = 2 if random.random() < 0.9 else 4
    return True

# 合并相同数字
def merge(nums):
    new_nums = [n for n in nums if n != 0]
    for i in range(len(new_nums) - 1):
        if new_nums[i] == new_nums[i+1]:
            new_nums[i] *= 2
            new_nums[i+1] = 0
    new_nums = [n for n in new_nums if n != 0]
    new_nums += [0] * (len(nums) - len(new_nums))
    return new_nums

# 旋转矩阵
def rotate(board):
    return [list(x)[::-1] for x in zip(*board)]

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

# 显示游戏面板和分数
def display(board, score):
    print("Score: %s" % score)
    for row in board:
        print(row)

# 移动游戏面板
def move(board, direction):
    if direction == "up":
        board = rotate(board)
        board = [merge(row) for row in board]
        board = rotate(board)
        board = rotate(board)
        board = rotate(board)
    elif direction == "down":
        board = rotate(board)
        board = rotate(board)
        board = rotate(board)
        board = [merge(row) for row in board]
        board = rotate(board)
    elif direction == "left":
        board = [merge(row) for row in board]
    elif direction == "right":
        board = [row[::-1] for row in board]
        board = [merge(row) for row in board]
        board = [row[::-1] for row in board]
    return board

# 游戏主函数
def main():
    board = init_board()
    score = 0
    generate_num(board)
    generate_num(board)
    display(board, score)
    while True:
        direction = input("Please input direction(up/down/left/right): ")
        board_new = move(board, direction)
        if board_new == board:
            continue
        board = board_new
        if not generate_num(board):
            print("Game over!")
            break
        score += 2
        display(board, score)
        if is_gameover(board):
            print("Game over!")
            break

if __name__ == "__main__":
    main()

这个游戏的分数是每次合并相同数字的总和，每次合并相同数字时，分数增加这两个数字的和。在游戏开始时，会随机生成两个数字2或4。玩家可以通过输入指令来移动数字，游戏的结束条件是游戏面板被填满了，没有可以合并的相同数字。
