Python

In this major python concept has been covered.

All about getting start with Python.

What is Python Programming ?

• Python is a Simple , high level and Object Oriented programming language which is created by Guido Van Rossum

• Python is also know as Interpreted scripting language , which is python code can be executed with or without compiling the Source code or the Python Script . That is python interpreter allows to execute the python code directly.

Why Python Programming?

• Python is famously known for its simplicity which is the code which is written in Python is less when compared to other programming languages like C, C++, java etc..,,,

• Python is Simple to learn and effective to use.

• Python support Dynamic Variable allocation , thus there is no need to use data types to declare the varible.

Python Versions

• Python consists of2 versions which is Python 2 and Python3 and this 2 versions differ a lot from each other.
• Example Python2 use print as print"Statement", where as Python3 use print as print("Statment").

Python Feature:

• Easy and simple to learn.

• Understandable and Readable.

• Interpreted Language.

• Supports in many platform.

• Free and Open Source.

• Object-Oriented Language(OOPs).

• Contains Large Standard Library.

• Supports GUI Programming.

Area of Application:

• Web Application.

• Desktop GUI Application.

• Software Development.

• Scientific and Numeric.

• Business Application.

• Console Based Application.

• Audio or Video based Application.

• Enterprise Application.

Install Python in Your Local Machine.

Click Here to download Python based on different Operating System and based on 32bit or 64bit.

Click Here - To download latest version of Python for Windows Operating System with 64bit.

Click Here - To download latest version of Python for Mac Operating System with 64 bit.

After downloading it , Install it like how we install other application.

After Installation of Python , To check its installation open comand prompt and enter Python --version to check the version of python installed in the machine.

Lets start

Python support interpreted type which is used to executed python code in interpreter(terminal).

But here i am using Scripting to compile the Python code and Execute the Python code which has compiled.

To compile and execute the python script file.

• First open any text editor like Notepad, Notepad++ etc...,,

• Here i am using Sublime Text editor.

• Then write the python code and save the file by using .py extension.

• Then open comand prompt and specify the file / folder location where the .py python file has been saved.

• To compile that .py python file type "python filename.py" and press Enter.

• If no error then respective output will be displayed on the screen.

Important Notes to Learner :

• Anything which is followed by hashtag(#) is consider as a comments. Comments play major role in this tutorial since Comments will be used to explain the syntax and how the program and program control flow in Python Program.

• Follow this README file to make this tutorial in effective way

• This python tutorial is divided as BASIC , INTERMEDIATE , ADVANCE
