如何在discord.py消息之间添加停顿？

Question

我有一个用python编程的discord机器人。 我希望机器人说笑话的第一部分，即time.sleep，然后讲笑话的第二部分（都在同一个变量中）。 这是我的代码：

if message.content.startswith('!joke'):
    a = 'Can a kangaroo jump higher than a house?' + time.sleep(3) + 'Of course, a house doesn’t jump at all.'
    b = 'Anton, do you think I’m a bad mother?' + time.sleep(3) + 'My name is Paul.'
    c = 'Why can\'t cats work with a computer?' + time.sleep(3) + 'Because they get too distracted chasing the mouse around, haha!'
    d = 'My dog used to chase people on a bike a lot.' + time.sleep(3) + 'It got so bad, finally I had to take his bike away.'
    e = 'What do Italian ghosts have for dinner?' + time.sleep(3) + 'Spook-hetti!'
    msg = random.choice([a, b, c, d, e]).format(message)
    await client.send_message(message.channel, msg)

这是控制台输出：

Ignoring exception in on_message
Traceback (most recent call last):
  File "C:\Python\Python36\lib\site-packages\discord\client.py", line 307, in _run_event
    yield from getattr(self, event)(*args, **kwargs)
  File "archie_official.py", line 138, in on_message
    a = 'Can a kangaroo jump higher than a house?' + time.sleep(3) + 'Of course, a house doesn’t jump at all.'
TypeError: must be str, not NoneType

你能帮助我吗？ 谢谢。

Answer 1

你不应该使用time.sleep所有的，因为它不会发挥好asyncio ，这discord.py是建立在。 相反，我们应该有一个成对的列表，随机选择一个，然后使用asyncio.sleep在消息之间暂停。

jokes = [
    ('Can a kangaroo jump higher than a house?', 'Of course, a house doesn’t jump at all.'),
    ('Anton, do you think I’m a bad mother?', 'My name is Paul.'),
    ('Why can\'t cats work with a computer?', 'Because they get too distracted chasing the mouse around, haha!'),
    ('My dog used to chase people on a bike a lot.', 'It got so bad, finally I had to take his bike away.'),
    ('What do Italian ghosts have for dinner?', 'Spook-hetti!')]

setup, punchline = random.choice(jokes)
await client.send_message(message.channel, setup)
await asyncio.sleep(3)
await client.send_message(message.channel, punchline)

你这一切都错了。

a = 'Can a kangaroo jump higher than a house?' + time.sleep(3) + 'Of course, a house doesn’t jump at all.' 

将不起作用，原因是因为您希望time.sleep(3)是一个字符串，对于您要从中获取的每个字符串（据我所知）。 需要做以下

await bot.say("Can a kangaroo jump higher than a house?")
time.sleep(3)
await bot.say('Of course, a house doesn’t jump at all.' )

当然，您需要将bot更改为客户端，但这基本上是您必须要做的。

不能正常工作的原因：执行a = "string" +func()+"string2 ; print(a)"会产生错误，因为您将所有字符串都视为字符串。
