Introduction to Python and Writing first program

Python is an open-source programming language, open-source refers to free availability and cost-effectiveness. 

Python is a cross-platform language- it means once the program is written in python, the same code can be executed on any operating system platform such as Windows, Linux, Unix, Mac, etc. python is object-oriented programming.

Python has a very huge library of built-in functions and is easy to learn. Using the python application will be able to connect to any major databases such as MySQL, Oracle, or PostgreSQL. 

Control structure in python is used to control the run of the python program. program is basically a set of instructions provided to the system. The program might be just straight execution or might be skipping a few statements and continuing run or jumping to statement and then again coming back to the original statement. 

Writing the first program and executing it

First of all, you need to have python installed on the machine in order to run python programs. 

you can download installed from https://www.python.org/downloads/windows, you can follow simple instructions from here, once the installation is done, just verify using the command python

Once you get confirmation that python is installed, write the below code in a text file and save it as hello.py

#This is first program of hello world

print("hellow world!!! :) ") 

Once the writing is done, open command prompt and cd to location when hello.py is kept.

and run the script/program using python hello.py

In this way, you can run the python program on your windows machine.
