为Discord.Py嵌套If和Else语句

Question

我一直在努力解决这个问题。我可以得到一张支票，但不能另外支票。我想确保用户不能提及自己并且如果他们从get_dollars中提取的资金少于0美元，他们就不能“抢劫”另一个用户。我已经尝试过"try, except, else, finally"并让它进行半工作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思考，如果我嵌套if和else语句，它会更好地工作。我得到一个if message.author == user.mention: UnboundLocalError: local variable 'user' referenced before assignmenterror尝试这种方式。

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))

就像帕特里克所说的那样，没有用户的定义。结束put user = message.mentions [0]，命令正常。
