My Discord Bot Returns "AttributeError: 'str' object has no attribute"

Question

我正在 Python 上构建一个简单的 discord 机器人，将 space 放在输入的每个字符和其他一些东西之间。

我的代码在这里：

import discord
import asyncio

client = discord.Client()

def bos(a):
    a=a.upper()
    a=a.replace("0", "SIFIR")
    a=a.replace("1", "BİR")
    a=a.replace("2", "İKİ")
    a=a.replace("3", "ÜÇ")
    a=a.replace("4", "DÖRT")
    a=a.replace("5", "BEŞ")
    a=a.replace("6", "ALTI")
    a=a.replace("7", "YEDİ")
    a=a.replace("8", "SEKİZ")
    a=a.replace("9", "DOKUZ")
    a=" ".join(a)

@client.event
async def on_ready():
    print('Logged in as')
    print(client.user.name)
    print(client.user.id)
    print('------')

@client.event
async def on_message(message):
    if message.content.startswith('*'):
        a = message.content[1:]
        await client.send_message(message.channel, a.bos(a))
        #counter = 0
        #tmp = await client.send_message(message.channel, 'Calculating messages...')
        #async for log in client.logs_from(message.channel, limit=100):
        #    if log.author == message.author:
        #        counter += 1

        #await client.edit_message(tmp, 'You have {} messages.'.format(counter))
    #elif message.content.startswith('!sleep'):
        #await asyncio.sleep(5)
        #await client.send_message(message.channel, 'Done sleeping')

client.run('token')

但是当我在 discord 上写 *test 时，终端 returns:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/discord/client.py", line 307, in _run_event
    yield from getattr(self, event)(*args, **kwargs)
  File "bot2.py", line 32, in on_message
    await client.send_message(message.channel, a.bos(a))
AttributeError: 'str' object has no attribute 'bos'

有人可以帮我修复这段代码吗？

Answer 1

bos 不是 str 上的方法；这是一个全局作用域的函数。而不是 a.bos(a)，只需使用 bos(a).

Answer 2

bos 是常规函数，而不是 str 方法。此外，在函数内部分配给 a 不会影响调用外部的参数；您需要 return 一个新字符串。

def bos(a):
    return " ".join(a.upper().
                      replace("0", "SIFIR").
                      replace("1", "BİR").
                      replace("2", "İKİ").
                      replace("3", "ÜÇ").
                      replace("4", "DÖRT").
                      replace("5", "BEŞ").
                      replace("6", "ALTI").
                      replace("7", "YEDİ").
                      replace("8", "SEKİZ").
                      replace("9", "DOKUZ"))


...
await client.send_message(message.channel, bos(a))
#                                          ^^^^^^
