How to join multiple channels using twitchdev python code - python-3.x

Question

I'm trying to make translate bot using twitchdev python code: https://github.com/twitchdev/chat-samples/blob/master/python/chatbot.py
I was able to get messages from channels and send translated text, but I cannot join multiple channels.
What I did below is making list of channels and call using for loop, but it only join to the last channel.
I tried to make another list of channels in def on_welcome(self, c, e) but it also works on the last channel (when I print self.channels in def on_welcome(self, c, e) it printed blank list, and when I print self.channel it only printed last channel)
Any suggestions are welcome.
import sys
import irc.bot
import requests
import config
class TwitchBot(irc.bot.SingleServerIRCBot):
def __init__(self, username, client_id, token, channels):
for channel in channels
self.client_id = client_id
self.token = token
self.channel = '#' + channel
# Get the channel id, we will need this for v5 API calls
url = 'https://api.twitch.tv/kraken/users?login=' + channel
headers = {'Client-ID': client_id, 'Accept': 'application/vnd.twitchtv.v5+json'}
r = requests.get(url, headers=headers).json()
self.channel_id = r['users'][0]['_id']
# Create IRC bot connection
server = 'irc.chat.twitch.tv'
port = 6667
print 'Connecting to ' + server + ' on port ' + str(port) + '...'
irc.bot.SingleServerIRCBot.__init__(self, [(server, port, 'oauth:'+token)], username, username)
def on_welcome(self, c, e):
print 'Joining ' + self.channel
# You must request specific capabilities before you can use them
c.cap('REQ', ':twitch.tv/membership')
c.cap('REQ', ':twitch.tv/tags')
c.cap('REQ', ':twitch.tv/commands')
c.join(self.channel)
def on_pubmsg(self, c, e):
# If a chat message starts with an exclamation point, try to run it as a command
if e.arguments[0][:1] == '!':
cmd = e.arguments[0].split(' ')[0][1:]
print 'Received command: ' + cmd
self.do_command(e, cmd)
return
def do_command(self, e, cmd):
c = self.connection
# Provide basic information to viewers for specific commands
elif cmd == "raffle":
message = "This is an example bot, replace this text with your raffle text."
c.privmsg(self.channel, message)
elif cmd == "schedule":
message = "This is an example bot, replace this text with your schedule text."
c.privmsg(self.channel, message)
def main():
if len(sys.argv) != 5:
print("Usage: twitchbot <username> <client id> <token> <channel>")
sys.exit(1)
username = config.twitch['botname']
client_id = config.twitch['cliendID']
token = config.twitch['oauth']
channels = ["channel1", "channel2"]
bot = TwitchBot(username, client_id, token, channels)
bot.start()
if __name__ == "__main__":
main()

Answer 1

In your main() function, you are establishing an object of the bot:
bot = TwitchBot(username, client_id, token, channels)
Instead of passing multiple channels to the same bot object, create multiple bot objects with single channels. I haven't tested this yet because Twitch updated their OAuth protocol and I haven't been through the docs.
You may need to thread them, and depending on what functions you implement it may not be thread-safe (just test before going into production). That'd probably look something like:
import threading
t1 = threading.Thread(target=TwitchBot, args=(username, client_id, token, channel1))
t2 = threading.Thread(target=TwitchBot, args=(username, client_id, token, channel2))
t1.setDaemon(True)
t2.setDaemon(True)
t1.start()
t2.start()
Once again, I haven't tested any of this but will likely have time in a few weeks to patch this in my own code after the holiday.
