Python, What is Python?

INTRODUCTION TO PYTHON LANGUAGE

In this section we will cover a brief introduction about Python and  syntax's for beginners

Python is a powerful high-level,interpreted,interactive,object-oriented,standalone programming language created in 1980's by Guido van Rossum.It's name came from MONTY PYTHON.

FEATURES OF PYTHON

• It has simple easy-to-use syntax,making it the perfect language for someone trying to learn computer programming for the first time.
• No compilation required, just run the script.
• Easy maintanance,portability,scalability,readability,
• It is an open source code.
• Can be Extended to C(Cython),Java(Jython), .NET(Ironpython) 
• Every memory allocation is done dynamically.
• Supports a tonn of libraries and Universal languages.
• Plays major role in Embedded system ie in automation.

what is an interpreter language?

An interpreter is a program that reads and executes code. This includes source code, pre-compiled code,and scripts. Common interpreters include Perl, Python, and Ruby interpreters, which execute Perl, Python, and Ruby code respectively.

COMPILER	INTERPRETER
C,C++,C#,JAVA	Python,RUBY,Perl,JAVA Scripting
Will Generate Object code.	No object code.
Whole source code will be treated as input.	Line by line execution of source code.
Compile will create separate executable file	File name itself is executable
Once the code is compiled successfully we can execute n number of times	Every time statements will be executed
Compiler needs more memory	Needs less memory with respect to compilers
Faster operation	Slower compared to compilers

What is IDLE?

IDLE is Python’s Integrated Development and Learning Environment.

IDLE has the following features:

• coded in 100% pure Python, using the tkinter GUI toolkit
• cross-platform: works mostly the same on Windows, Unix, and Mac OS X
• Python shell window (interactive interpreter) with colorizing of code input, output, and error messages
• multi-window text editor with multiple undo, Python colorizing, smart indent, call tips, auto completion, and other features
• search within any window, replace within editor windows, and search through multiple files (grep)
• debugger with persistent breakpoints, stepping, and viewing of global and local namespaces
• configuration, browsers, and other dialogs
