Twitch bot a bytes like object is required, not 'str'

Question

Hello Guys i am trying to learn how to make a twitch bot for my friends' channel they streams regulary and sometimes i join them. Now i was able to make the bot join to the chat room but i couldn't figure out administration part so the bot suppoused to timeout any body uses the word "swear" instead i get this error:

tmi: :tmi.twitch.tv 001 wasddabulyuasede_bot :Welcome, GLHF!
:tmi.twitch.tv 002 wasddabulyuasede_bot :Your host is tmi.twitch.tv

A string is an abstraction, representing a sequence of unicode codepoints. To turn a string into a sequence of bytes, you need to encode your string, aka decide on how you want to represent your text on the wire. For Twitch, use UTF-8:

full_msg = "PRIVMSG #{} :{}".format(cfg.CHAN, msg)
msg_encoded = full_msg.encode("utf-8")
sock.send(msg_encoded)

Doesn't `socket.send` require bytes? Are you not giving a `str` here? – Paco H. Sep 18 '17 at 14:59
`socket.send` expects bytes: https://docs.python.org/3/library/socket.html#socket.socket.send – Felk Sep 18 '17 at 15:01
Yes, on the first line you go from str to bytes. But isn't the result of the format of the second line a str? – Paco H. Sep 18 '17 at 15:06
`File "Bot.py", line 15, in chat sock.send("PRIVMSG #{} :{}".format(cfg.CHAN, msg_encoded)) TypeError: a bytes-like object is required, not 'str'` i still get the same error – walrus Sep 18 '17 at 15:10
Please update your answer to include the new code and also show what line is the one mentioned in the error message – Felk Sep 18 '17 at 15:19
i don't get any errors but not sure if it works properly.thanks for help – walrus Sep 18 '17 at 16:17
