So i've been working on this code that i got online and it is a chat server code.
This is the code-
# import needed modules:
from socket import * # get sockets, for well, sockets
import string # string functions
import time # for sleep(1) function
# define global variables
HOST = '' # Symbolic name meaning the local host
PORT = 4000 # Arbitrary non-privileged server
endl = "\r\n" # standard terminal line ending
userlist = [] # list of connected users
done = 0 # set to 1 to shut this down
kAskName = 0 # some constants used to flag
kWaitName = 1 # the state of each user
kOK = 2
# class to store info about connected users
class User:
def __init__(self):
self.name = ""
self.addr = ""
self.conn = None
self.step = kAskName
def Idle(self):
if self.step == kAskName: self.AskName()
def AskName(self):
self.conn.send("Name? ")
self.step = kWaitName
def HandleMsg(self, msg):
print "Handling message: ",msg
global userlist
# if waiting for name, record it
if self.step == kWaitName:
# try to trap garb initiall sent by some telnets:
if len(msg) < 2 or msg=="#": return
print "Setting name to: ",msg
self.name = msg
self.step = kOK
self.conn.send("Hello, "+self.name+endl)
broadcast(self.name+" has connected."+endl)
return
# check for commands
if msg == "quit":
broadcast(self.name+" has quit.\n")
self.conn.close()
userlist.remove(self)
return
# otherwise, broadcast msg
broadcast( self.name+": "+msg+endl )
# routine to check for incoming connections
def pollNewConn():
try:
conn, addr = s.accept()
except:
return None
print "Connection from", addr
conn.setblocking(0)
user = User();
user.conn = conn
user.addr = addr
return user
# routine to broadcast a message to all connected users
def broadcast(msg):
for u in userlist:
u.conn.send(msg)
# MAIN PROGRAM
# set up the server
s = socket(AF_INET, SOCK_STREAM)
s.bind(HOST, PORT)
s.setblocking(0)
s.listen(1)
print "Waiting for connection(s)..."
# loop until done, handling connections and incoming messages
while not done:
time.sleep(1) # sleep to reduce processor usage
u = pollNewConn() # check for incoming connections
if u:
userlist.append(u)
print len(userlist),"connection(s)"
for u in userlist: # check all connected users
u.Idle()
try:
data = u.conn.recv(1024)
data = filter(lambda x: x>=' ' and x<='z', data)
data = string.strip(data)
if data:
print "From",u.name,': ['+data+']'
u.HandleMsg(data)
if data == "shutdown": done=1
except:
pass
for u in userlist:
u.conn.close()Now my problem is that when i try to connect, there is a traceback error
(Traceback (most recent call last):
File "E:\Python Files\Chat Server.py", line 98, in <module>
s.bind(HOST, PORT)
File "<string>", line 1, in bind
TypeError: bind() takes exactly one argument (2 given))
I've tried to switch the code around to make it work, but nothing seems to be working. Could use some help?
