class DataCreate(commands.Cog):

        self.client = client
    async def view_cash(self, member):

    async def addtobal(self, member, amount):
        path = 'bal_' + member + '.txt'
        if not os.path.isfile(path):
            datacreate = DataCreate
            await datacreate.createdatacash(member)
        getcash = GetCash
        bal_amount = getcash.view_cash(member)
        output = int(bal_amount) + int(amount)
        datacreate = DataCreate
        await datacreate.writefile(member, output)





@client.command(pass_context=True)
async def daily(ctx):
    numlist = []
    x=99
    person = str(ctx.message.author.id)
    for x in range(99,600):
        x+=1
        numlist.append(x)
    secure_random = random.SystemRandom()
    cash = secure_random.choice(numlist)
    print(str(cash))
    cashmodify = CashModify
    print('ran')
    await cashmodify.addtobal(person, cash)
    getcash = GetCash
    channel = client.get_channel(ctx.message.channel.id)
    channel.send("You gained " + str(cash) + ' credits, spend wisely!")

我的源代码在上面，我希望这足够了

出现错误missing 1 required positional argument: 'amount'

此错误显示在：await cashmodify.addtobal(person, cash)

我一直在尝试用python 3.7编写一个带有不和谐重写的经济机器人，我决定这次让自己更容易的是将它们保留在类中，然后在需要时使用它们，但是只要我运行命令不一致，它表示我缺少一个称为“金额”的必需位置参数。我尝试过从字符串和整数切换输入，但我回头看了一下该类，它仍然无法正常工作。

我尝试过的另一件事是删除命令。Cog，但这仍然行不通。因此，我很感谢任何人都能给我的帮助

Answer 1

创建类的实例并调用其方法之一时，self（代表类的实例）将作为参数传递给它。

此代码不会创建您的类的实例，而只是创建一个类对象：

>>> cashmodify = CashModify
>>> cashmodify
<class '__main__.CashModify'>

addtobal方法的定义与此addtobal(self, member, amount)相似，而您正在像这样addtobal(person, cash)对其进行调用。

由于未创建类CashModify的任何实例而导致错误：没有self属性，因此您的person和cash变量被传递为self和member自变量，什么也不会传递给amount。

要解决此问题，您必须根据您的__init__方法实例化您的类（创建它的实例），并将其传递给客户变量：

cashmodify = CashModify(client)

当明确输入Discord.py类定义时未获取变量
