Python: How does a python program take input from user ?

Question

I wanted to do a little project for learning Python. I thought a chat system will be good as it isn't something that I have ever done.

I wanted to know what will I need? I think that would require me these

1 learn network/socket programming
2 find a free server to host my chat server
3 GUI development for clients

-I wanted to know whether these are all that I would need or are there more things?
-Will I need to learn a web framework like Django?
-Will I need to learn something for database management like sql for handling people's account names and password?

Is google appengine good for hosting the website or should I look up at django hosting websites?

Answer 1

I know two ways to provide input from keyboard.
1. raw_input("Enter no:")
2. input ("Enter no.")
