How to install Python

1. Test if Python is already installed on your system
2. Download Python if it is not already installed on your system
3. Check if it's correctly added to the PATH or add it so that you can call it directly from the terminal.

How to test if Python is already installed on your system

• Mac : Open up the spotlight and search for terminal
• Windows : W + R and write cmd
• Linux : Ctrl + Alt + T for ubuntu

Check the version if python is installed

python --version

If you end up with an error on both commands then python might not be installed on your system.

If you still end up with an error then you will need to tell your computer where your Python is installed by editing the PATH.

On MAC or LINUX

export PATH="the/path/where/your/python/executable/is:$PATH"

For windows it's a bit more complex.
