Chat bot joins server, receives chat, but can't send anything FIXED

        username = re.search(r"\w+", response).group(0) # return the entire match
        message = CHAT_MSG.sub("", response)
        print(username + ": " + message)
        for pattern in cfg.PATT:
            if re.match(pattern, message):
                ban(s, username)
                break

So I’m confused on why it’s not sending a message at:

CHAT_MSG = re.compile(r"^:\w+!\w+@\w+\.tmi\.twitch\.tv PRIVMSG #\w+ :")
chat(s, "ITS ME")

I’m not very familiar with IRC and I’m still confused after reading up on it, so any help would be awesome.
EDIT: Fixed, this is the fixed code:

                break

#cfg.py
HOST = "irc.chat.twitch.tv"              # the Twitch IRC server

RATE = (20/30) # messages per second

PATT = [    #not used yet
    r"swear",
    # ...
    r"some_pattern"
]

Figured out the issue, my cfg.py CHAN variable had an extra ‘#’ in it
