0x00 - Python
Python - A easy to set up, dynamic scripting language, great for small quick projects but can be used for most about everything. Python can be set up on most OS's, I will be covering Windows and Debian(Or any other Linux distribution with APT installed).



0x01 - Software
In order to run any Python script what so ever you will need the Python engine.

Windows
Python for windows can be downloaded at www.python.org, http://python.org/ftp/python/2.7/python-2.7.msi
Just install it as you wish, and remember where you installed it. By default its c:\Python27 or something along those lines.

Open CMD and navigate to the folder you installed Python( cd c:\Python27 ). Then write python and hit enter. If you get something like this:

Python 2.7 (r27:82525, Jul  4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)] on win
32
Type "help", "copyright", "credits" or "license" for more information.
>>>

You have done it right and are ready to start scripting!


Linux
To install Python run this command:

• sudo apt-get install python

Then run "python", if you get something like this:

Python 2.5.2 (r252:60911, Jan 24 2010, 14:53:14)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

You have done it right and are ready to start scripting!



0x02 - Starting Python scripting
Python scripting is fairly easy, create .py files and stuff some Python script inside it and run "python YourScript.py". Here is a few examples:

Simple Hello World print

Code: [Select]

print "Hello World"

Variable print

Code: [Select]

Variable1 = "Hello World"
print Variable1

Math + print

Code: [Select]

Var1 = 10
Var2 = 10
Var3 = Var1 + Var2
print Var3

Nice work ande

[hanorotu]

Thanks, this is the alternative for the java/javascript.

It's looking good so far. Pretty easy to code in this. More natural.

[Ullen]

Thanks ande. I'm trying to learn Python.

Hey admin, can u please post tutorials for RUBY language. It would be a great help.

[rxsmed]

Well i'm learning Python as a first programming language and i can tell, its cool and easy to learn.
I found this book to be interesting as a first one and theres also this one here. (First is PDF, second is HTML).
Avoid "learning python the hard way" cuz it sucks.

Bye.

[Corrupted_Fear]

so glad to see a python tutorial here. And "Learning python the hard way" isn't a good beginner book, but more like a second level book. It gives you examples for you to copy and then explains how they work. Not a good starter if you have no idea how to work they Python language.

Sorry for a very late reply. But oh well. I am afraid I don't know ruby all that well, but I encourage anyone who do to make one like this.

python happens to be my latest darlin though new in programming/ screepting i can already see its going to be cool.
one problem though, MODULES are such a hustle to find.is there any way to update and install all modules at a go?

If you are not linux, hopefully debian based. A lot of python modules can be found with aptitude and easily installed from there.

If not, or you cant find a package version of the module you want. Here is everything you need to know: http://docs.python.org/2/install/index.html

Care to show how to run the interactive interpreter?
I've been trying from Pythons documentation and some ebook i got from here but i can't seem to get it down.

[Kulverstukas]

Care to show how to run the interactive interpreter?

Start -> Run -> type in "python" -> press enter -> should work.
If not then do:
Start -> Run -> type in "cmd" -> press enter -> cd into where you installed python -> type in "python" -> should work.

[EMOKDOOM]

Oh, i'm sorry, think i explained wrong.

I wanted to run an output box. Like the one on codeacademy or learnpthon.org
Is it even possible or do i need some other Python interpreter?

Regardless, isn't the Python shell not good enough?
