Python字符串split()方法读取IRC时导致索引错误

Question

我正在创建一个 twitch 聊天机器人来阅读我的信息流中的聊天内容。但是当我尝试将传入的字符串 .split() 分成单独的字符串以隔离用户名和消息时，它会显示一个额外的'和 ["'"]。当我尝试按索引单独打印字符串时，出现索引错误。

以下是连接twitch聊天的代码，以及当我在聊天中输入“test”时的结果。

from settings import *
import socket
import threading

class twitch:
    def __init__(self, host, port, nick, pwd, channel):
        self.s = socket.socket()
        self.s.connect((host, port))
        self.s.send(bytes("PASS " + pwd + "\r\n", "UTF-8"))
        self.s.send(bytes("NICK " + nick + "\r\n", "UTF-8"))
        self.s.send(bytes("JOIN #" + channel + " \r\n", "UTF-8"))
        self.s.send(bytes("PRIVMSG #" + channel + " :" + "Connected " + "\r\n", "UTF-8"))
        self.alive = True

        readerthread = threading.Thread(target=self.read_chat)
        readerthread.start()

    def read_chat(self):
        while self.alive:
            for line in str(self.s.recv(1024)).split('\\r\\n'):
                if "PING :tmi.twitch.tv" in line:
                    print(time.strftime("%H:%M:%S"), "PONG :tmi.twitch.tv")
                    s.send(bytes("PONG :tmi.twitch.tv\r\n", "UTF-8"))
                else:
                    print(line)
                    parts = line.split(":")
                    print(parts)

def main():
    tc = twitch(HOST, PORT, NICK, PASS, CHANNEL)

将字符串（行）打印到控制台会生成：b':username!username@username.tmi.twitch.tv PRIVMSG #username :test

但是，当我拆分字符串并打印字符串（部分）列表时，它会产生以下结果： [“b”，'用户名！用户名@用户名.tmi.twitch.tv PRIVMSG #username'，'测试'] ' ["'"]

您正在读取字节。因此，b'...'。
What does the 'b' character do in front of a string literal?

将其转换为字符串，然后进行处理。
Convert bytes to a string?

链接中的代码。

>>> b"abcde"
b'abcde'

# utf-8 is used here because it is a very common encoding, but you
# need to use the encoding your data is actually in.
>>> b"abcde".decode("utf-8") 
'abcde'
