Instead of defining it there, do it in the constructor (__init__ function).
class SomeClass(object):
def __init__(self):
# Set the socket parameters
self.addr = ('','')
self.UDPSock = socket(AF_INET,SOCK_DGRAM)
this will still be available to all your methods inside the class. You will have to prefix it with "self" everywhere you use it, since you're saying "this instance of this class owns this variable", not "This class as a whole has this single instance of a variable"
class SomeClass(object):
def __init__(self):
# Set the socket parameters
self.addr = ('','')
self.UDPSock = socket(AF_INET,SOCK_DGRAM)

Hey everyone,
I'm a beginner Python and PyGTK developer so sorry for the stupid question.I have a class named Client which is meant to send data to a server via UDP socket. here is a snippet of the
I get undeclared global variable error for addr and UDPSock.Code:class Client: # Set the socket parameters addr = ('','') UDPSock = socket(AF_INET,SOCK_DGRAM) # callback for getting the IP address def connect_callback(self, widget, entry): hostName = entry.get_text() addr = (hostName,21567) #callback to send the message in the testfield def send_mesg_callback(self, widget, textfield): t_msg = textfield.get_buffer() if(UDPSock.sendto(t_msg,addr)): print "Sending message '",t_msg,"'....." ...
But I can't access my global variables it gives me an error, even when I put a 'self.' infront of the global variables for example infront of UDPSOCK. what am i doing wrong here?
-Thank you
