Basic question

I've been studying python for 2 weeks now and got stucked in the following problem: for j in range(10): print j if(True): j=j+2 print 'interno',j What happens is that "j=j+2" inside IF does not change the loop counter ("j") as it would in C or Java, for example. Am I missing so

Basic question about sockets and security

Hi all, I'm just starting out in sockets/network programming, and I have a very basic question...what are the 'security' implications of opening up a socket? For example, suppose I've written a simple chat server and chat client. The server opens a socket, listens on
