Hi friends this post was taken in Drupal workshop for third year.I like to share this with you.
Before getting into this I like to say that all the information I took here are from various sites.The Description of all the modules are liable but not sure whether the no. of downloads of each module are correct,it may differ.
*****MOST IMPORTANT INFORMATION THESE DESCRIPTION ON MODULES ARE VERY BRIEF THEY DOES MORE JOB IN LIVE WEB ENVIRONMENT BUT IT GIVES US SOME KNOWLEDGE.
BEFORE LEARNING THIS YOU SHOULD HAVE KNOWN WHAT IS MODULE? TO KNOW THAT YOU SHOULD HAVE DOWNLOADED DRUPAL IN YOUR SYSTEM,THEN THIS POST WILL HELP YOU.IF YOU DON'T KNOW ABOUT MODULE DON'T WORRY JUST LEARN IT IN WIKIPEDIA OR DRUPAL.ORG.THIS GIVES BASIC KNOWLEDGE ON MODULES.*****
OK LETS GO,
1.Administration menu—22910 downloads
Administration menu module it is useful for the beginners in Drupal.It provides a CSS-based menu at the top of your website.It contains not only regular menu items - local tasks are also included, giving you extremely fast access to any administrative resource and function your Drupal installation provides.
2.Content Construction Kit—19795 downloads
CCK is used for handling the contents of the Drupal site.For example there may be many admins and user for every site with different mode of access.This module helps in handling the content posted by different users at different point of time.
1)The time of post.
2)The date last updated
3)The user who modified data.
This module allows Drupal to replace textarea fields with the FCKeditor - a visual HTML editor, sometimes called WYSIWYG editor. This HTML text editor brings many of the powerful WYSIWYG editing functions of known desktop editors like Word to the web. It's relatively lightweight and doesn't require any kind of installation on the client computer.
There is a demo for this editor you can go to this site for playing with this editor.
4.Views module—17747 downloads
The Views module provides a flexible method for Drupal site designers to control how lists and tables of content are presented.
This tool is essentially a smart query builder that, given enough information, can build the proper query, execute it, and display the results. It has four modes, plus a special mode, and provides an impressive amount of functionality from these modes.
5.PATHAUTO –11994 downloads
The Pathauto module automatically generates path aliases for various kinds of content (nodes, categories, users) without requiring the user to manually specify the path alias. This allows you to get aliases like /category/my-node-title.html instead of /node/123. The aliases are based upon a "pattern" system which the administrator can control
6.BACKUP AND MIGRATE--10671 downloads
Backup and Migrate simplifies the task of backing up and restoring your Drupal database or copying your database from one Drupal site to another. It supports gzip, bzip and zip compression as well as automatic scheduled backups.
Tokens are small bits of text that can be placed into larger documents via simple placeholders, like %site-name or [user]. The Token module provides a central API for modules to use these tokens, and expose their own token values.
8.Lightbox2 –9928 downloads
The Lightbox2 module is a simple, unobtrusive script used to overlay images on the current page. It's a snap to setup and works on most modern browsers.The module places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths. It keeps users on the same page. Clicking to view an image and then having to click the back button to return to your site is bad for continuity
This module adds a webform nodetype to your Drupal site. Typical uses for Webform are questionnaires, contact or request/register forms, surveys, polls or a front end to issues tracking systems.
Submissions from a webform are saved in a database table and can optionally be mailed to a nominated e-mail address upon submission. Past submissions are viewable for users with the correct permissions.
Webform includes some simple statistical tools to help in form design and evaluation and also allows the whole table to be downloaded as a csv file for detailed statistical analysis.
A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can. The CAPTCHA module provides this feature to virtually any user facing web form on a Drupal site.
You can download the pdf from the groups file option.
Ok these are the top ten modules of drupal.Thank you.

Hello friends in this blog I am going to write about Python,its installation,its comparisons with other languages and some thing about VPython as well as SciPY.
If you want to download the e-book for python download it from either clicking the picture or clicking the link given below
I am not a well experienced in python but I just want to share stuffs which I learnt over intenet.
All the informations in this Blog are written after verifications.
WHAT IS PYTHON?
Python is the high-level programming language which concentrates more on its code readability.It uses indentation for block delimiters.Python is free and open source software.
sudo aptitude install python2.5
python 2.6.4 for windows
Python gives more concentrations on the structure and the indentation of the code so we need to be careful with respect to the indentation of the code.
>>>if 1 + 1 == 2:
>>>if 1+2 == 3:
OUTPUT for the code is
consider this code
>>>if 1 + 1 == 2:
>>> if 1+2 == 3:
File "hllo.py", line 4
if 1 + 2== 2:
Thus Python gives more importance to the readability for the code.Python uses whitespace indentation, rather than curly braces or keywords, to delimit blocks.An increase in indentation comes after certain statements; a decrease in indentation signifies the end of the current block.
Python is case sensitive.So the careful usage is important.
There are many statements supported by Python let me say some of them
* The if statement, which conditionally executes a block of code, along with else and elif (a contraction of else-if).
* The for statement, which iterates over an iterable object, capturing each element to a local variable for use by the attached block.
* The while statement, which executes a block of code as long as its condition is true.
* The try statement, which allows exceptions raised in its attached code block to be caught and handled by except clauses; it also ensures that clean-up code in a finally block will always be run regardless of how the block exits.
* The class statement, which executes a block of code and attaches its local namespace to a class, for use in object-oriented programming.
* The def statement, which defines a function or method.
* The with statement (from Python 2.6), which encloses a code block within a context manager (for example, acquiring a lock before the block of code is run, and releasing the lock afterwards).
* The pass statement, which serves as a NOP and can be used in place of a code block.
* The assert statement, used during debugging to check for conditions that ought to apply.
* The yield statement, which returns a value from a generator function.
* The print statement, which writes a value to an output stream
Python uses def for defining a function it is much similar to that of the function keyword in c or c++
Despite being dynamically typed, Python is strongly typed, forbidding operations that are not well-defined (for example, adding a number to a string) rather than silently attempting to make sense of them.

COMPARISONS OF PYTHON WITH OTHER LANGUAGES
I don't have much knowledge on various languages so I found it in a site I share this with you
Java vs Python
1. interpreted vs. compiled is a big productivity win for Python
2. dynamic typing is a big productivity win for Python
3. Java is way faster than Python
4. minimal scaffolding is a big productivity win for Python. Makes programming more pleasant not to have to build all the infrastructure.
5. mostly first class functions a big win for Python.
6. built-in lists/arrays and hashes/dictionaries a big win over Java  and library based collections. Java 5.0 fixes some of this but in Java collections still seem tacked on rather than integrated.
7. dynamic code loading in Python is a big win. Yes you can do it in Java but again, the cruft.
8. There is some weirdness in Python lexical scoping of names. The documentation for each has several warnings about edge cases where names don't bind in the expected way. This gives me a queasy feeling although in practice it may not matter. Another win for static type checking.
9. Java 'Comparable' interface ugly compared to Python built in comparison mechanisms that require only that a single function be implemented to get the full set of comparison operators. An example of excess Java scaffolding.
10. lack of multiline comments in Python was annoying
Fine in this you may or may not understand certain terms like DYNAMIC TYPING,SCAFFOLDING,dynamic code loading,multiline comments.If your comfortable with these terms you skip this else let me explain
It is nothing but we can declare a variable without any data type but the value has the data type. For example in Python,if you need a variable, you simply come up with a name and start using it as a variable.
sam = 5 or sam = "hello";
SCAFFOLDING : This is the meta-programming method of building databases.Usally used in frameworks like Django which uses Python.It is nothing but a simple command to create a CRUD application
dynamic code loading:Automatic loading of script.Used both in java as well as python but python is better than java.
multiline comments:We cannot comment more than one line in Python.
Python has a large standard library, commonly cited as one of Python's greatest strengths,providing pre-written tools suited to many tasks.But let me say some of the library used for SCIENTIFIC PURPOSES and also developing 3-D models.
NumPy is an extension to the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large library of high-level mathematical functions to operate on these arrays.
x = linspace(0, 2*pi, 100)
y = sin(x)
SciPy is an open source library of algorithms and mathematical tools for the Python programming language.SciPy contains modules for optimization, linear algebra, integration, interpolation special functions, FFT, signal and image processing, ODE solvers and other tasks common in science and engineering. It has a similar audience to applications as MATLAB, GNU Octave, and Scilab.
VPython is the Python programming language plus a 3D graphics module called Visual. VPython allows users to create objects such as spheres and cones in 3D space and displays these objects in a window. Real-time, navigable 3D animations are generated as a side effect of computations. This makes it easy to create simple visualizations, allowing programmers to focus more on the computational aspect of their programs. The simplicity of VPython has made it a tool for the illustration of simple physics, especially in the educational environment.
from visual import * #import the visual module
rod = cylinder(pos=(0,2,1), axis=(5,0,0), radius=1)
We can learn more about Python by learning from e-books available over internet as well as from e-learning sites.
