Question

下面的代码在我使用!luck xx时工作正常，并且当金额低时会说金额低，但是当我使用!luck -xx时它仍会不断增加金额。
那么如何禁用-xx金额

@bot.command(pass_context=True)
async def luck(ctx, amounty: int):
    primary_id = ctx.message.author.id
    if primary_id not in amounts:
        await bot.say("not registered")
    elif amounts[primary_id] < amounty:
        await bot.say("low balance")
    else:
        amounts[primary_id] -= amounty
        a = random.randint(1,2)
        if a == 1:
            amounts[primary_id] += amounty * 2
            await bot.say("You Won")
        else:
            await bot.say("You lost")

只需检查数字是否为负数，如果为负则返回空值

  if amounty<0:
    await bot.say("Can't use a negative number")
    return
