Edit:
Which of the following computer programming languages should I learn after I'm finished learning Python?
- C
- C++
- C#
- Java

Python is a great choice!

I don't think being a better programmer means knowing more languages. Learn a language properly and master the skills involved in concepts such as OOP. I would strongly suggest that you read Dive Into Python (<- link). It's a great tutorial that goes far beyond knowing the syntax. Read it even if you don't plan to code too much in Python.

Hi null !

First welcome to programmers' world ...

In my opinion learning a new language have to be useful for you, of course your first language is the language wich instaure all basics reflexes that a programmer have to master, but knowing other languages for doing other things that programming for desktop can be a good thing.

So I recommend you to learn first PHP or HTML for internet development or if you want a really oriented object language you can learn from know Java wich is really similar to C# and a little bit to python.
And If you want to stay on desktop applications, I think that .NET languages are really easy and powerful (like C#) and with a total freedom to develop on the net (ADO.net for example).

Personallly I never programmed in python ... and I don't understand why you choosed this language as your first language, I still even now, terrorized by vars which start with $, may be because of C pointers .

Good luck and as Umang said first develop your skills in Python before attacking an other language.

and Sorry for my bad English, malikcpp

I would have to say start with C...learning to code in C provide you with a bit more insight into what is *actually* going on in the computer as well as enforce good programming habits.

This is why I prefer C as a starting language...it's a challenge...but well worth it.

Well, I don't like reading books and programming books is not an exception. I prefer reading reference on things I'm interested in or reading a bunch of tutorials if I don't know how to do first steps, but that's me, you have to find your way to learn.

Back to topic. It depends on what you want to code. As Umang said, knowing many languages doesn't mean you are a good programmer. I used to think so too, I wanted to learn all languages and went for this goal until I understood that I do not improve, I just learn many syntaxes and that all languages are more or less same. So now I'm using C++ the most. And that would be my suggestion. Learn C/C++ (similar languages, but you have to pick up the one you prefer, or take both (many people use C++ with C included, because C is a bit faster in most cases, but C++ is OOP which makes programming easier). Those languages have been used for so long and have many things you can use in any other language. C++ is either used in many programs development because it's very fast and the code is pretty eye-friendly (at least I think so )

Well. It's up to you, but I vote for C/C++
