Introduction to Programming: Python, Java and Javascript

This is an overview of writing a basic converter program in 3 different languages, Python, Java, and JavaScript. I personally have used this as an exercise to learn new languages particularly the process of getting variables, manipulating them, and returning an output. These concepts will help with almost any program that you want to make in the future.

The video took a little longer to talk through than I anticipated, but 15 mins per language is hopefully acceptable. Again just something I hope can help people get started.

Source code:

• Python
• Java
• JavaScript

A few books and other sites that are helpful - Intro to Python, Learn Java in 8 hours, W3 schools, and more. Here are a few links. There are also countless tips and tricks just by Googling and searching through https://stackoverflow.com/.

• Chuck Severance, Python for Informatics, (C) 2009 - 2013,

• Ray Yao, Java in 8 Hours, (C) 2015, see on Amazon
  Several other books around basic Java are also extremely helpful, but Ray Yao's book is a great way to start. 
• "JavaScript Tutorial", W3 schools, https://www.w3schools.com/js/default.asp
• Download Python from https://www.python.org/downloads/
• Download JavaScript JDK https://jdk.java.net/ <- in Linux this is available as a package in your package manager (Ubuntu/Debian distros: apt search openjdk)

Here as well is a quick video about how to setup the OpenJDK package in Linux. Alternatively, Windows, MacOS, and RedHat Distros can install from Oracle directly or at the above link.
