为Discord.Py嵌套If和Else语句

Question

我已经为此命令苦苦挣扎了一段时间。 我可以拿一张支票上班，但不能拿另一张。 我想确保用户不会提及自己，并且如果他们从get_dollars提取的钱少于0美元，那么他们就不能“抢劫”另一个用户。 我尝试过"try, except, else, finally"并使其半成品，但它会吐出两条消息，而不是一条消息。 然后，我尝试下面的代码，以考虑是否嵌套if和else语句，它将更好地工作。 我得到一个if message.author == user.mention: UnboundLocalError: local variable 'user' referenced before assignment错误以这种方式尝试if message.author == user.mention: UnboundLocalError: local variable 'user' referenced before assignment 。

if message.content.startswith('!rob'):
        if message.author == user.mention:
            await client.send_message(message.channel, "{} you cant rob yourself! 👊".format(message.author.mention))
        else:
            if get_dollars(message.author) < 0:
                await client.send_message(message.channel, "{} you can't even afford a gun.".format(message.author.mention))
            else:
                for user in message.mentions:
                    if (get_dollars(user)) < 1:
                        await client.send_message(message.channel, "{} is too broke to rob 🤣".format(user.mention))
                    elif steal <= 3:
                        print("{} catches {} slippin and sticks them up for ${} 😨🔫".format(message.author.mention, user.mention, stealdollars))
                        await client.send_message(message.channel, "{} catches {} slippin and sticks them up for ${} 😨🔫".format(message.author.mention, user.mention, stealdollars))
                        remove_dollars(user, stealdollars)
                        add_dollars(message.author, stealdollars)
                    elif steal == 4:
                        print("{} gets arrested trying to rob {} and has to post $250 bail 👮🚨".format(message.author.mention, user.mention))
                        await client.send_message(message.channel, "{} gets arrested trying to rob {} and has to post $250 bail 👮🚨".format(message.author.mention, user.mention))
                        remove_dollars(message.author, 250)
                    elif steal >= 5:
                        print("{} kicks {}'s door down but doesn't find any cash 🤬".format(message.author.mention, user.mention))
                        await client.send_message(message.channel, "{} kicks {}'s door down but doesn't find any cash 🤬".format(message.author.mention, user.mention))

就像Patrick所说的那样，没有用户的定义。 最终将user = message.mentions [0]放进去，命令运行正常。
