我有一个命令，你需要Ping/提及某人作为必需的Arg，但你如何通过提及获得他们的userid？
示例：
async def id(ctx, ping):
ctx.send(f"{ping}, your user id is {the person metioned's id}")
试试这个：
async def id(ctx, ping: discord.Member = None): # Assuming that 'ping' is a user you are mentioning
await ctx.send(f"{ping.mention}, your user id is {ping.id}")
这是假设论点"ping"是不和谐的。会员
