These are IRC status codes, provided by the server to indicate when particular operations have
completed. These are used by the program to know when it has received the required list of
names from the IRC server. Next, set up the variables for the server connection by entering
the following lines:
irc = {
}
The first line tells Python to create a dict data type. Short for dictionary, this allows multiple
variables to be stored in a single master variable—in this case,
ables can then be recalled later in the program. Although you could write this program with-
out using dicts to store variables, it would make the program significantly more difficult to
read. The dict begins with the opening curly brace, and ends with the closing curly brace on
the final line.

you want to customise the program to use a different server, change the domain name here.

Set up a second dict to store the user-specific variables by typing in the following lines:
