This tells Python that when the
complete list of names to the standard output before blanking the
line— —is important: without it, each time the loop runs it will add users'
names = []
names to the list even though they already exist from an earlier run .
Finally, finish the program by entering the following lines:
time.sleep(irc['namesinterval'])
s.send('NAMES %(channel)s\r\n' % irc)
This tells Python to wait the
request for user names and beginning the loop again . Be careful to set
reasonable value—if the IRC server receives too many requests in too short a space of time,
it may forcibly disconnect you for flooding .
Save the program as
ircuserlist.py
option in the Run menu or from the terminal by typing
the program first runs, it may take a while to connect to the server; once connected, how-
ever, the list of names (see Figure 11-7) should refresh quickly . To quit the program, press
CRTL + C .
