Hi LQ,
Iam learning python and obviously on linux platform. I want to know what are the tools we have to start with.
Can somebody advise some sources, I am more interested in tools and applications that can make my learning go smooth.

First you have to download and install Python from your distribution using some package managers (easiest), or you can install manually. See here for Python download.
All new ones to Python should read the documentation. Read the tutorial, as well as the beginner guides on the site.

what tools to use? Just Python (and probably if you wish, an editor ).
Everything you need to know is at the documentation site.

install "idle" which is an ide for python.
Download the bok Byte of Python from http://www.swaroopch.com/notes/Python.
It has both python 2.x and python 3 tutorials. It is a very good book.

Have fun.

Thanks a lot. That should keep me busy atleast for now.

For a Python editor, I recommend UliPad. It's what I used to write my MPD client.

I've also used vim (which is great once set up) and Eclipse with PyDev (which is great and has PyLint integration), but UliPad should be more convenient to start with.

I suggest to find a problem first, that's where it always begins. If you have something to solve (by using python), you've got a goal and hopefully a will to solve it. Then you do it and learn in the process. If you only read books, you'll gather theoretical knowledge which you'll forget in some time, and when you really need to do something, you'll end up wondering how it went and then have to resort to the book again. Avoid that Books are good sources of information, but not as efficient as learning through trial and error. The same applies to mathematics, for example: you can read tons of solutions, but without working through the actual problems you'll never be able to solve them without outside help.

Emacs is an option, though I've recently started learning vim too. I sort of dislike the heavy "environment"-of-an-editor-things, because they're not on every machine I work at, they're heavier than simpler tools (like vim) and often require graphical user interface on top of every other thing. And yet Python is textual programming

If you can't figure anything else out, start off by writing Hello World app. Then write a program that can handle Huffman encoding and decoding. Then write a server-client chat program that can work with multiple clients. That should keep you going for a while...

Thanks, I am using VIM as python IDE. Din't try any other yet.
Infact VIM seems perfect as if now.

Kindly do NOT start installing Python straightaway !

I would recommend to open a terminal and type python as follows and pres enter:
and see if you get something like above. Kindly do this before trying to install Python ! Since Python is installed by default on most of the major distributions.

+1 for running "python" on the command line, you probably have it installed already.

Also, if you do so, it will come up with an interactive prompt where you can type Python code and have it interpreted as you go.
