ABOUT PYTHON:
=============

What is the Python?
===================
Application:
===========
	collection of programs
		multi tasking
	==> three types:
		1) Desktop Applications ==> Notepad, Excel, Paint, Calculator etc.
		2) Web Applications ==> gmail, youtube etc.
		3) Distributed Applications
			Phonepe/Paytm
				by any banking Subscriber
			Bank Balance 
				check balance
					Phonepe ===> bank server (App)
						<====
						UPI
						<====
						display	

1) General Purpose Programming Language
2) High Level Programming Language
3) Easy Programming Language

Syntax:
======
	set of guidelines for making the code/program

History of Python:
==================
	Guido Van Rossum
	1980 and early 1990
	NRI (National Research Institute), Netherlands

Roots for python:
	C ==> Procedural
	C++ ==> Objective nature
	Perl & Shell Scripting

1980:
	BBC
		Mount's Python Circus


Python Features:
===============
1) High level
2) Easy
3) General Purpose
4) Open Source & Free 
5) Portable
	X-app ==> Python ==> Windows
		==> extending to Linux/Mac-OS
6) Extendible
7) Dynamically Typed 

High Level Programming languages
	1) Statically Typed : C
	2) Strongly Typed
	3) Dynamically Typed

In C:
	datatype data-name = value;
	ex: int x = 123; correct
	int y = 1.23; correct // y = 1
In Java:
	datatype data-name = value;

	ex: int x = 100; correct
	int x = 1.23; Incorrect

In Python:
	data-name = value;
	x = 1.23 // float
	c = 100; // int


len(), print(), id() etc.

Python Applications:
====================
1) Web applications
2) Desktop Applications
3) Distributed Applications
4) DataScience
5) Artificial Intelligence
6) Scripting etc.
=============================================================
PYTHON SETUP:
=============
1) Download and Install python software
========================================
==> we should check whether the python software is already in our computer or not:
	window-search bar ==> cmd ==> open command prompt ==> type a command: "python --version"
==> when we are not having the python software:
	we should download it.
use this link:
	https://www.python.org/downloads/
to download the python software
==> After the downloading, we can run that file
	select the last check list (python PATH)
	click on "Install Now".
2) Download IDE (Integrated Development Environment)
====================================================
	PyCharm

https://www.jetbrains.com/pycharm/download/?section=windows

3) create the python file
4) Write program
5) Run the program

print "hello"
print("hello")
