A "Hello, World!" program generally is a computer program that outputs or displays the message "Hello, World!". Such a program is very simple in most programming languages, and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code.
In this post I will show you how to print "Hello, World!" in Python
This is first post and I am scared
Step 1: Download and Install Python
[skip this step if you have already installed it]
Just head to https://python.org/download/ and download the install the program supported by your os, i.e. .msi for windows and .dmg for mac
