我开始在 Pycord 库中制作 Python Discord 机器人。我想制作一个可以在多台服务器上运行的机器人，并且每台服务器都有不同的值。因此，为了做到这一点，我制作了一个字典，它将所有这些值存储在一个嵌套字典中。但是，当我尝试更改一个嵌套字典的值时，它会更改其他嵌套字典中的值。

代码：

server_ids = {}
default_server_vals = {'beetle_game_started': False, 'beetle_message_id': None,
'beetle_message_channel': None, 'beetle_player_1': None, 'beetle_player_2': None, 'beetle_game_on': False, 'player1_list' : [], "player2_list":[]}

@bot.event
async def on_ready():
    print('logged in')
    for i in bot.guilds:
        global server_ids
        global default_server_vals
        server_ids[str(i.id)] = default_server_vals
    print(server_ids)  # Generate server IDS
@bot.event
async def on_guild_join(guild):
    server_ids[str(guild.id)] = default_server_vals

@bot.slash_command(guild_ids=testing_servers, name="beetle", description="2 Player game")
async def beetle(ctx):
    print(server_ids[str(ctx.guild.id)].get('beetle_game_on'), server_ids[str(ctx.guild.id)].get('beetle_game_started'))

    if server_ids[str(ctx.guild.id)].get('beetle_game_on') == False and server_ids[str(ctx.guild.id)].get('beetle_game_started') == False:
        await ctx.respond("Game starting! React to join.")
        game_start_embed = discord.Embed(title="React to join beetle game! (2 Players Only)",
                                         colour=discord.Colour.green())
        game_start_embed.add_field(name="GAME RULES", value="""There are two players. There is one dice! The first player to finish the beetle drawing wins.
    Rolling a 1 – Body

    Rolling a 2 – Head

    Rolling a 3 – A leg

    Rolling a 4 – An eye

    Rolling a 5 – An antenna

    Rolling a 6 – The tail
    The first player to roll all 6 wins. However, the head and body must be drawn first to draw the other beetle parts.""")
        message = await ctx.send(embed=game_start_embed)
        await message.add_reaction("😎")
        print(ctx.guild.id)
        server_ids[str(ctx.guild.id)]['beetle_game_started'] = True
        print(server_ids)
        server_ids[str(ctx.guild.id)]['beetle_message_id'] = message.id
        server_ids[str(ctx.guild.id)]['beetle_message_channel'] = message.channel
    elif server_ids[str(ctx.guild.id)].get('beetle_game_started'):
        await ctx.respond("Someone already started a game! Try and join them.")
    else:
        await ctx.respond("There is already a beetle game playing!")

on_ready会获取机器人已处于的服务器 IDS，并将其放入全局server_ids变量中。然后将嵌套字典作为字典的服务器 ID 值。但是，当我尝试编辑嵌套字典的值（在 beetle 斜线命令中）时，它会更改所有其他嵌套值。

例如，当我尝试更改beetle_game_started的嵌套字典值时，它会打印以下内容：

{'912361242985918464': {'beetle_game_started': True, 'beetle_message_id': None, 'beetle_message_channel': None, 'beetle_player_1': None, 'beetle_player_2': None, 'beetle_game_on': False, 'player1_list': [], 'player2_list': []}, '938245167880753202': {'beetle_game_started': True, 'beetle_message_id': None, 'beetle_message_channel': None, 'beetle_player_1': None, 'beetle_player_2': None, 'beetle_game_on': False, 'player1_list': [], 'player2_list': []}}

它以某种方式改变了服务器 IDS 的两个嵌套字典的值（“beetle_game_started”的值）。我该如何在不改变其他字典值的情况下改变一个嵌套字典的值？
