為Discord.Py嵌套If和Else語句

Question

我已經為此命令苦苦掙扎了一段時間。 我可以拿一張支票上班，但不能拿另一張。 我想確保用戶不會提及自己，並且如果他們從get_dollars提取的錢少於0美元，那么他們就不能“搶劫”另一個用戶。 我嘗試過"try, except, else, finally"並使其半成品，但它會吐出兩條消息，而不是一條消息。 然后，我嘗試下面的代碼，以考慮是否嵌套if和else語句，它將更好地工作。 我得到一個if message.author == user.mention: UnboundLocalError: local variable 'user' referenced before assignment錯誤以這種方式嘗試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所說的那樣，沒有用戶的定義。 最終將user = message.mentions [0]放進去，命令運行正常。
