Create Your first website using Django

This blog will guide you to create a website within a very short period of time. You will also come to know about files that are provided initially to create a website.

The website is basically a collection of web pages, and these web pages can be static or dynamic. Static web pages display the exact information whenever a person visits it. But, Dynamic web pages are capable of producing different content for different visitor from the same source code.  To have in-depth knowledge about Python and Django, you can enroll for Python Django online training.

Django is basically a web framework, where coding is done with the Python programming language by following the MVC pattern. This MVC (Model-View-Controller) pattern comprises of three basic aspects, i.e., data access, business logic & presentation layer. MVC expresses the core of the solution to a problem while allowing it to be adopted for each system.

Django is a prominent member of the new generation web framework. It is designed to let you focus on the fun while easing the pain of repetition. It lets you build deep, dynamic, interesting sites in an extremely short time.

In order to create a website in Django, you first need to create a project. This project is made by a command provided by cmd of startproject. Through Django-admin file, a new project is created, you can further create individual web pages in this project. A project, which is created, gives you some files automatically to manage up the website. A project is a collection of setting for an instance of Django, including database configuration, Django-specific option & application specific settings. Once you have created a project with startproject command, it will give a separate directory and this directory will initially contain –manage.py and –Mysite (folder name provided while creating project). This folder contains other Python files like __init__.py, settings.py, urls.py, wsgi.py.

Further, to set up a database for your website, you first need to have a database. Django supports four types of database engines, namely, PostgreSQL, Sqlite3, MtSQL and Oracle. In order to write code for your webpage, you need to create a Python file separately, which holds all functionalities of your web page. This Python file is stored with other files like settings.py, etc. in the same folder. Meanwhile, it provides the access of that function in your url. In this way Django supports the concepts of loose coupling which manages files separately. So, with all these steps you can create many web pages for your website in just a couple of minutes.

Make your Programming interesting with Python

Automating your redundant tasks is desirable. Right? It basically makes your life easier. We call a process automatic when it is certain, independent of any control or conscious.

You must have spent so much time in renaming a bunch of files in a folder, editing number of cells on excel files. These tedious computer task can be automated using simple and coherent program that even non-programmers can take advantage of it. Being the most beginner-friendly programming language Python is the option that quickly comes to mind. The best thing about Python is that the graph of things you actually learn and implement goes simultaneously. Python is truly a language which one enjoys thoroughly.The actual Python code is very close to pseudo code. It is as practical as illustrative.

What Python is known for?

Python seems all the rage these days. It is a well-designed language with a comprehensive standard library, clean syntax and documentation, widespread deployment and the immediacy of a “scripting” style language. The greatest strength of Python is developing applications rapidly.

 Python is known for its user friendliness and ease to learn. The Zen of Python itself says “Simple is better than complex”, “If the implementation is easy to explain, it may be a good idea”, “Now is better than never”. Once you understand how to frame simple code in Python, very soon you start using powerful pieces of pre-existing code i.e, Python modules .Python standard library hands over rich modules to effortlessly perform impressive and useful feats of scripting prowess. It does not take an age to program, remember Python was created with programmers in mind so it’s simple and quick to write code in it. Additionally it is fast to learn you could reasonably proficient in Python in less than two months. Talking of non-techies, Python is easy to pick up and learning.

 Source: http://westmarch.sjsoft.com/2012/11/zen-of-python-poster/

Some people find Python to be most natural language as a full-fledged code looks like a pseudo code which is intended for human reading rather than machine reading.

The charm of Python lies in its power provided with ease. Some of the biggest and most known software like YouTube, Dropbox, Quora, Instagram, Bit Torrent, Spotify, Reddit, Totalspy, Pinterest, BitBucket, Blender3D are written in Python.

 What is Python best for?

The answer to this question is almost everything. Your imagination is the limit, as you could create anything you dream off. You can write code to automate redundant computer tasks, ,small to large web projects, GUI stuff, Console Stuff , massive applications, quick – hack scripts ,robotics program in raspberry pi.

With a concluding note Python is best for small to large scale applications from accomplishing small bat files to large development projects, skilled programmers to non-techie people.

A tutorial for beginners with interactive examples

Avro is an open source framework within Apache’s Hadoop project. That deals with data exchange services and data serialization for Hadoop. By using Avro, Big data can be exchanged among programs written in any language. Also it uses RPC to send data. Programs can efficiently serialize data into files or into messages by using this service.

Following key advantages of Avro:

1. Schema evolution

·         It requires schemas while reading and writing the data.

·         Most exciting feature of Avro.

·         Avro schemas are defined using JSON.

sample data is defined as below (Student.avsc):

  {

       "type": "record",

       "name": "student",

      "fields":

    [

       {"name": "name", "type": "string"},

       {"name": "age", "type": "int"},

       {"name": "emails", "type": {"type": "array", "items": "string"}},

       {"name": "student", "type": ["student","null"]}

      ]

}

   2. Untagged data 

Two ways to encode data (binary or JSON).

Switching JSON protocol to binary format to achieve better performance.

Makes compact data encoding and faster data processing.

Used to implement validation for a JSON protocol.

  3. Dynamic typing

·         Serialization and deserialization without generating code.

·         It is a set of name (field name)-value (Avro supported value type) pair.

·         It is referred to as “generic” as compared to “static” code generation approach.

Very easy to use.

  Avro support various datatypes-

Primitive type names:

ü  null : no value

ü  boolean : a binary value

ü  int : 32-bit signed integer

ü  long : 64-bit signed integer

ü  float : single precision (32-bit) IEEE 754 floating-point number

ü  double : double precision (64-bit) IEEE 754 floating-point number

ü  bytes : sequence of 8-bit unsigned bytes

ü  string : Unicode character sequence

Sample coding of Primitive Types:

{"type": "string"}

  Complex type names:

ü  records

ü  enums

ü  arrays

ü  maps

ü  union

ü  fixed

Sample coding of Complex Types:

{    "type": "enum",

      "name": "Suit",

       "symbols" : ["SPADES", "HEARTS", "DIAMONDS", "CLUBS"]

}

{      "type": "array", "items": "string"   }

{       "type": "map", "values": "long"     }

  Avro utilizes a compact binary data format –that helps to find results in fast serialization times. And its concept of schema is similar to Protocol Buffers, but Avro is far better than Protocol Buffers, because Avro works natively with MapReduce.

Schema Resolution: A reader of Avro data, whether from an RPC or a file, can always parse that data because its schema is provided. But  that schema may not be exactly the schema that was expected.We call the schema used to write the data as the writer's schema, and the schema that the application expects the reader's schema. For example, if the data was written with a different version of the software than it is read, then records may have had fields added or removed.

Apache Avro is one of the unique serialization framework.

In the upcoming post, we'll cover the program for serialization/deserialization of data using Avro and also see how Avro works.

R: Is ‘R’ a language like other programming languages?

With the growing volume of Big Data there is need for better decision making and data analysis. Analysis of data helps us to arrive at accurate and meaningful information and makes sense out of scattered data in the huge database.

INTRODUCTION TO ‘R’

R is a programming language and an amazing tool used for Data analysis and Statistical Graphics. It adds an easy visualization to your data by showing it in Graphical forms. It is free, and widely used by professional statisticians and market analysts. It's free, open source, powerful and highly extensible.

HISTORY OF ‘R’

The R language is a terminology of S which was designed in the 1980s by John Chambers at Bell labs and has been in widespread use in the statistical community since. It was grown up by Robert Gentleman and Ross Ihaka of the University of Auckland. R has been with us since 1993.

WHY R?

R can alone be used for complex analysis and very useful for those who are tired of using Excel for analysis. The emergence of data sciences leads R to an unmarkable growth. We have almost everything built-in in R to reduce programming overhead. R provides Statistical and Programming features both. Many mathematical operations (mean, median, matrix, bargraphs, histograms, etc.) can be computed in a single command.

APPLICATION AREAS OF ‘R’

Bioinformatics

Operations Research

Statistics

Artificial Intelligence

Linear Algebra

Machine learning

Data Mining

Data visualization

Analysis of Big Data

Making predictions

  R has tremendous growth over the last few years. R has picked up the pace of popularity because of its application areas. Beside above areas R can be used in many other fields.

HOW ‘R’ DIFFERENT FROM OTHER PROGRAMMING LANGUAGES?

R has a lot of prepackaged stuff that's already available. Because it's a programmable environment that uses command-line scripting, you can store a series of complex data-analysis steps in R. That lets you re-use your analysis work on similar data more easily. We are not required to deal with complex parts like pointers as we need to do in C, C++, or any other programming languages. There is no need to specify data types against variables. Other languages are difficult to learn and take a longer period to learn.

Get you system ready for Python Programming.

Python is a widely used high level language. It is an object oriented language like the C++, java etc. Python is widely used these days in many applications. The code in python is smaller and less complex than the other language which makes it an easy language to learn.

How Python is different from other languages?

• Python programs are nearly 3-5 times shorter than equivalent Java programs

• Python programmer does not waste time declaring the types of arguments or variables

• Python supports a programming style that uses simple functions and variables without engaging in class definitions

• Python shines as a glue language, and is used to combine components written in C++

What is Python Interpreter?

You need to install the Python interpreter on your computer. This is the program that reads Python programs and carries out their instructions; you need it before you can do any Python programming

• A python code (somefile.py) when imported creates a file (somefile.pyc) in the same directory. Let us say the import is done in a python shell. After the import I change the code a bit and execute the imported functions again to find that it is still running the old code. This suggests that *.pyc files are compiled python files similar to executable created after compilation of a C file, though I can't execute *.pyc file directly.

• When the python file (somefile.py) is executed directly (./somefile.py or python somefile.py) no .pyc file is created and the code is executed as is indicating interpreted behavior.

• Python will fall under the category of byte code interpreted language.

• .py source code is first compiled to byte code as .pyc and then further executed.

• This byte code can be interpreted by (CPython), or JIT compiled.

• Python source code (.py) can be compiled to many different byte codes also like the IronPython (.Net) or Jython (JVM).

• When you run something like python script.py, the script is converted to the bytecode and then the interpreter/VM/CPython–really just a C Program–reads in the python bytecode and executes the program accordingly.

• There is basically a giant switch statement present inside the CPython interpreter that says "if the current opcode is so and so, do this and that".

So this is Python language which is object oriented like Java or C++. It is used in a wide variety of applications like gaming, dropbox, testing etc.
