I am new to any scripting language. But, Still I worked on scripting a bit like tailoring other scripts to work for my purpose. For me, What is the best online resource to learn Python?
Some Online Resources:
http://docs.python.org/tut/tut.html - Beginners
http://diveintopython.org/ - Intermediate
http://www.pythonchallenge.com/ - Expert Skills
http://docs.python.org/ - collection of all knowledge
Some more:
If you're a beginner, try my book A Byte of Python.
If you're already experienced in programming, try Dive Into Python.
If you need to learn python from scratch - you can start here: http://docs.python.org/tut/tut.html - good begginers guide
If you need to extend your knowledge - continue here http://diveintopython.org/ - good intermediate level book
If you need perfect skills - complete this http://www.pythonchallenge.com/ - outstanding and interesting challenge
And the perfect source of knowledge is http://docs.python.org/ - collection of all knowledge
Its a bit long winded sometimes but it tells you all you need to know to get going.
These are unvaluable online reference tools:

A good python blog for beginners: http://www.learningpython.com/
I think Python Challenge is great.
It's not about learning Python (syntax) but presents you small and fun riddles. Solving the riddles is based on Python but you can use whatever fits (your calculator, bash scripts, Perl...). After you solved one, you get to see how others have solved it and can discuss the pros & cons of the different ways.
Very nice to get a feel for how things could be done (smart) in Python. This site works especially well if you know a bit about other scripting languages or the commandline, etc.
I consider ActiveState's Python community to be a great resource. Also DZone Snippets can be useful.
I first ran across Software Carpentry looking at lists of python tutorials.. but its a lot more than a tutorial on python. turns out what I really learned was how to use subversion, and that none of my projects are better suited to python than to perl... yet.
The Python tutorial is actually pretty good.
There's also a video series on showmedo about python.
Between those two resources, you should have more than enough to learn the basics!
You can look at Building Skills in Python, also. It presumes some level of experience in programming.
If you're really new, try Building Skills in Programming. It includes a lot of background and fundamentals.
