【问题描述】：

我遇到了一个问题，我尝试将邀请链接打印到控制台中，但结果却打印出来了

<generator object Client.create_invite at 0x000001D310A183B8>
<generator object Client.create_invite at 0x000001D310A65410>

我正在使用此代码：

@client.event
async def on_ready():

    #await client.change_presence(game=Game(name="with humans"))
    print("Logged in as " + client.user.name)
    await asyncio.sleep(3)
    for server in client.servers:
        for channel in server.channels:
            channel_type = channel.type
            if str(channel_type) == 'text':
                invitelinknew = client.create_invite(destination=channel, xkcd=True, max_uses=100)
                print(str(invitelinknew))
                break

我尝试将print(invitelinknew) 更改为print(str(invitelinknew))，但并没有改变结果

编辑：

使用 invitelinknew2 = list(invitelinknew) 使用生成器时出现新错误和print(invitelinknew2):

【问题讨论】：

如输出所示，它是generator object。您需要消耗生成器。例如list(invitelinknew) 或 set(invitelinknew) 或其他内容，具体取决于返回的类型。

我怎么知道生成器是什么类型的，所以我可以用正确的方式来消费它
先试试print(list(invitelinknew))，然后打印出来，根据你看到的你可以决定如何消费（list除外）。

【解决方案1】：

根据documentationcreate_invite是协程，需要await关键字

更改您的代码以包含它，例如

if channel.type == discord.ChannelType.text:
  invitelinknew = await client.create_invite(destination=channel, xkcd=True, max_uses=100)
  print(invitelinknew.url)
