Exercise 0 - Introduction

Follow the steps to install Python 3. As Python 2 is retiring in a few years, it’s only logical to use Python 3!

Installation - Python 3

Step 1 - Head over to this Python download page and download the installer for Python 3.6.x.
Step 2 - Double click the installer and begin installing.
Step 3 - You can either choose to set the environment variables (PATH and PATHEXT) upon installation or set it manually once the installer finishes.
Step 4 - Open a command prompt and verify that python -V shows the version installed. If you get any errors, bug Aru and ask him to set the env variables for you!

Step 1 - It’s already installed! Just fire up a terminal and check the version.
Step 2 - If your Python version is 2.x.x, you can install Python 3 using the following commands in your terminal (for debian based distributions).
```
  $ sudo apt-get update
  $ sudo apt-get install python3.6
```

Step 3 - For LTS versions use the following repository.

  $ sudo add-apt-repository ppa:fkrull/deadsnakes

Use the following commands in your terminal.

  $ sudo add-apt-repository ppa:webupd8team/sublime-text-3
  	$ sudo apt-get update
  	$ sudo apt-get install sublime-text-installer`
