Forum Thread: Python IRC bot, v3

Python IRC bot, v3

Beware, the code is quite ratty. A goal in this version was to be able to update/add commands without having to restart the bot. Mission accomplished.

botim.py:

import re
import select
from time import sleep

#Global Variables
host    = "irc.darchoods.net"   #This is the IRC server variable.
port    = 6667                  #This is the port
nick    = ""             #Bot name
ident   = ""             #ID to NickServ with this name
servername = "bla"
realname= ""             #Bots real name for server identification
password= ""
channel = "#nullbytez"          #This is the channel name

CRLF = '\r\n'
# Examples
# Considered adding something to make it a little more channel independant
