Python for Beginners

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace.

Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

Data Analytics and Machine Learning are the keys to the future and Python plays a significant role in this domain. Most of the Data analytics software including Pandas, NumPy, SciPy, StatModels, Bokeh, Scikit-learn are Python based. Python Deep learning packages include TensorFlow, Keras, Elephas. Anaconda is a free and open-source distribution of the Python and R programming languages for scientific computing (data science, machine learning applications, large-scale data processing, predictive analytics etc) that aims to simplify package management and deployment.

AngularJS - OpenSource JavaScript Framework

AngularJS is an open-source JavaScript framework. Its goal is to augment browser-based applications with Model–View–Controller (MVC) capability, reduce the amount of JavaScript needed to make web applications functional. These type of apps are also known as Single-Page Applications.

The Philosophy of Angular:

Angular is built around the belief that declarative programming is better than imperative programming when it comes to building UIs and wiring software components together, while imperative code is excellent for expressing business logic.

Design goals:

1. Decouple DOM manipulation from app logic. This improves the testability of the code.
2. Regard app testing as equal in importance to app writing. Testing difficulty is dramatically affected by the way the code is structured.
3. Decouple the client side of an app from the server side. This allows development work to progress in parallel, and allows for reuse of both sides.
4. Guide developers through the entire journey of building an app: from designing the UI, through writing the business logic, to testing.
5. Make common tasks trivial and difficult tasks possible.

Notable Features:

1. Two Way Data-Binding
2. Templates
3. MVC
4. Dependency Injection
5. Derivatives

Notable Angular Directives:

1. ng-repeat: Instantiate an element once per item from a collection.
2. ng-show & ng-hide: Conditionally show or hide an element, depending on the value of a boolean expression.
3. ng-switch: Conditionally instantiate one template from a set of choices, depending on the value a selection expression.

Lua Scripting Language

Lua is a lightweight multi-paradigm programming language designed as a scripting language with "extensible semantics" as a primary goal. Lua is cross-platform since it is written in ISO C. Lua has a relatively simple C API compared to other scripting languages.

Lua is intended to be embedded into other applications, and accordingly it provides a robust, easy-to-use C API. The API is divided into two parts:

1. Lua core

2. Lua auxiliary library.

Lua Features:

1. Lua is commonly described as a “multi-paradigm” language, providing a small set of general features that can be extended to fit different problem types, rather than providing a more complex and rigid specification to match a single paradigm. Lua, for instance, does not contain explicit support for inheritance, but allows it to be implemented relatively easily with metatables. Similarly, Lua allows programmers to implement namespaces, classes, and other related features using its single table implementation; first-class functions allow the employment of many powerful techniques from functional programming; and full lexical scoping allows fine-grained information hiding to enforce the principle of least privilege.

2. In general, Lua strives to provide flexible meta-features that can be extended as needed, rather than supply a feature-set specific to one programming paradigm. As a result, the base language is light – the full reference interpreter is only about 150 kB compiled - and easily adaptable to a broad range of applications.

3. Lua is a dynamically typed language intended for use as an extension or scripting language, and is compact enough to fit on a variety of host platforms. It supports only a small number of atomic data structures such as boolean values, numbers (double-precision floating point by default), and strings. Typical data structures such as arrays, sets, lists, and records can be represented using Lua’s single native data structure, the table, which is essentially a heterogeneous associative array.

4. Lua implements a small set of advanced features such as first-class functions, garbage collection, closures, proper tail calls, coercion (automatic conversion between string and number values at run time), coroutines (cooperative multitasking) and dynamic module loading. By including only a minimum set of data types, Lua attempts to strike a balance between power and size.

Python Integration with C++/Java

There are two, standard built-in ways of integrating Python with a Programming Language like C++/Java.

The first is writing an extension, which involves creating a wrapper for C that Python imports, builds, and then can execute.

A second built-in way of integrating these languages is called embedding, and is where C++/Java are given direct access to the Python interpreter.

PHP

PHP => Hyper Text PreProcessor

PHP is a server-side, HTML-embedded, cross-platform scripting language--quite a mouthful. In simpler terms, PHP provides a way for you to put instructions in your HTML files to create dynamic content. These instructions are read and parsed by the web server; they never actually make it to the browser that is displaying the page. The web server replaces your PHP code with the content that the code was written to produce.

PHP can be configured to run either as a server module or as a standalone CGI script. At the time of this writing, the server-module version is only production-ready for the Apache web server on Unix systems. The CGI version runs with all web servers on both Unix and Windows 95/98/NT. On the Windows platform (as of PHP Version 4), the server module is being developed to work with ISAPI, NSAPI, and WSAPI, which means the server module will eventually work with Microsoft's IIS, Netscape's Enterprise Server, and O'Reilly's WebSite. See http://www.php.net/ for availability details.

The PHP language itself borrows concepts from other common languages, such as C and Perl. If you have some experience with one of these languages, you should feel right at home with PHP. In addition to the core language, PHP provides a wide variety of functions that support everything from array manipulation to regular expression support.

Database connectivity is one popular use for PHP. PHP supports a large number of databases natively and many others are accessible through PHP's ODBC functions. Through this database connectivity, it is possible, for example, to take a company's database of products and write a web interface to it using PHP.

PHP Frameworks:

1. Akelos

2. Symfony

3. PHPDevShell

4. CodeIgniter

5. Prado

6. CakePHP

7. ZooP

8. Zend

9. QPHP

VBScript

VBScript (short for Visual Basic Scripting Edition) is an Active Scripting language developed by Microsoft. The language's syntax reflects its history as a limited variation of Microsoft's Visual Basic programming language.

VBScript is installed by default in every desktop release of the Windows Operating System (OS) since Windows 98[1] and may or may not be included with Windows CE depending on the configuration and purpose of the device it is running on. It initially gained support from Windows administrators seeking an automation tool more powerful than the batch language first developed in the late 1970s.

A VBScript script must be executed within a host environment, of which there are several provided on a standard install of Microsoft Windows (Windows Script Host, Windows Internet Explorer). Additionally, The VBScript hosting environment is embeddable in other programs, through technologies such as the Microsoft Script control (msscript.ocx).

Regular Expressions

A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression (or if a given regular expression matches a particular string, which comes down to the same thing).

Regular expressions can be concatenated to form new regular expressions; if A and B are both regular expressions, then AB is also a regular expression. In general, if a string p matches A and another string q matches B, the string pq will match AB. This holds unless A or B contain low precedence operations; boundary conditions between A and B; or have numbered group references. Thus, complex expressions can easily be constructed from simpler primitive expressions like the ones described here. For details of the theory and implementation of regular expressions, consult the Friedl book referenced above, or almost any textbook about compiler construction.

A brief explanation of the format of regular expressions follows. For further information and a gentler presentation, consult the Regular Expression HOWTO, accessible from http://www.python.org/doc/howto/.

Regular Expressions :

^ matches the beginning of a string.

$ matches the end of a string.

\b matches a word boundary.

\d matches any numeric digit.

\D matches any non-numeric character.

x? matches an optional x character (in other words, it matches an x zero or one times).

x* matches x zero or more times.

x+ matches x one or more times.

x{n,m} matches an x character at least n times, but not more than m times.

(abc) matches either a or b or c.

(x) in general is a remembered group. You can get the value of what matched by using the
groups() method of the object returned by re.search.

Python Overview

Python is an dynamic object-oriented programming language that can be compared with Java and Microsoft's .NET-based languages as a general-purpose substrate for many kinds of software development. It offers strong support for integrating with other technologies, higher programmer productivity throughout the development life cycle, and is particularly well suited for large or complex projects with changing requirements.

Python's key strengths include:

1. Prototyping in Python is quick and easy, and often results in development of the final system in Python. The agile nature of the language, and the ease of refactoring code makes for rapid development directly from the initial prototype.

2. Application scripting is a snap with Python's tight integration with C/C++ and Java. Python was designed from the ground up to be embeddable and serves as an excellent choice as a scripting language for customization or extension of larger applications.

3. Software Testing benefits from Python's strong integration and text processing capabilities, and Python comes with its own unit testing framework.

4. Web development from simple CGI scripting to high-end web application development with mega-frameworks such as Django and Turbogears, the Zope application server, Plone content management system, Quixote web application framework, or a even a home-grown solution based on Python's extensive and easy to use standard libraries. Python provides interfaces to most databases, powerful text processing and document processing facilities, and plays well with other web technologies.

5. Numeric and scientific applications make use of the Python Imaging Library, VTK and MayaVi 3D Visualization Toolkits, Numeric Python, ScientificPython and many other tools available for numeric and scientific applications. Many of these are supported by the Enthought Python Distribution.

6. Desktop development using wxPython, PyQt, or PyGtk for high-quality GUI applications. Protect your investment by basing on open technologies, with deployment to most operating systems. Support for other GUI frameworks, such as MFC, Carbon, Delphi, X11, Motif, and Tk, is also available.

Popular Python IDEs:

• Eclipse with PyDev
• Eric
• IDLE

• Komodo IDE
• PyCharm
• Wing IDE

Python Popular Full-Stack Web Frameworks

Link : http://wiki.python.org/moin/WebFrameworks

A web application may use a combination of a base HTTP application server, a storage mechanism such as a database, a template engine, a request dispatcher, an authentication module and an AJAX toolkit. These can be individual components or be provided together in a high-level framework.

These are the most popular high-level frameworks. Many of them include components listed on the WebComponents page.

1. Django (0.96.1 Released 2007-10-26) a high-level Python Web framework that encourages rapid development and clean, pragmatic design

2. Pylons (0.9.6.2 Released 2008-05-28) a lightweight Web framework emphasizing flexibility and rapid development. It combines the very best ideas from the worlds of Ruby, Python and Perl, providing a structured but extremely flexible Python Web framework. It's also one of the first projects to leverage the emerging WSGI standard, which allows extensive re-use and flexibility but only if you need it. Out of the box, Pylons aims to make Web development fast, flexible and easy. Pylons is built on top of Paste (see below).

3. TurboGears (1.0.4.4 Released 2008-03-07) the rapid Web development megaframework you've been looking for. Combines CherryPy, Kid, SQLObject and MochiKit. After reviewing the website check out: QuickStart Manual

4. web2py (currently version 1.37) Everything in one package with no dependencies. Development, deployment, debugging, testing, database administration and maintenance of applications can be done via the provided web interface. web2py has no configuration files, requires no installation, can run off a USB drive. web2py uses Python for the Model, the Views and the Controllers, has a built-in ticketing system to manage errors, an internationalization engine, works with MySQL, PostgreSQL, SQLite , Oracle, MSSQL and the Google App Engine via an ORM abstraction layer. web2py includes libraries to handle HTML/XML, RSS, ATOM, CSV, RTF, JSON, AJAX, XMLRPC, WIKI markup. Production ready, capable of upload/download of very large files, and always backward compatible.

5. Grok (0.13 Released 2008-06-23) is built on the existing Zope 3 libraries, but aims to provide an easier learning curve and a more agile development experience. It does this by placing an emphasis on convention over configuration and DRY (Don't Repeat Yourself).

6. Zope (2.10.4 Released 2007-07-04, 3.3.1 Released 2007-01-14, Zope 3.4.0c1 Released 2008-01-31) Being the grandaddy of Python web frameworks, Zope has grown into a family of frameworks over the years. Zope 1 was released in 1999. Zope 2 is both a web framework and a general purpose application server, today it is primarily used by ContentManagementSystems. Zope 3 is both a standalone framework and a collection of related libraries, which are also included with newer releases of Zope 2. All of the Zope frameworks include the ZODB, an object database for Python.
