There are guides out there. And to find them, we use what's called a search engine. I recommend google.

However, I'll leave this open in case anyone wants to recommend you a guide that is particularly good or give you tips/pointers.

I learned most of python from here:
http://www.learnpython.org/
Pretty good explanations.

Yes use the tutorials from the site Akmal posted, very helpful, where I had started to!
Python isn't as powerful as many other programming languages but probably the best place to start
Lots of Reading, Testing, Patience, etc...
Worth it in the end,
Goodluck (:
