What is Tkinter:

Tkinter is Python's de-facto standard GUI (Graphical User Interface) package.

What is Atom:

Atom is a text editor used to build Python code. https://atom.io/

Atom Runner needs to be added for ease of testing code.

Click Packages/Settings View/Install Packages/Themes.

In Install Packages search for atom-runner.

Click Install.

Change the font size for Atom Runner by opening:

/home/tommy/.atom/packages/atom-runner/styles/atom-runner.less

Change the font size to 150%. This will make it easier to red when there are errors in the code.

Note: Atom must be restarted for these changes to take affect.

Note: A header (Shebang) may need to be added to all code to allow Atom to find the

Python3 files. To find what the header needs to be go to the terminal and type: which Python3.

My terminal returns: /usr/bin/python3.

My header will read: #!/usr/bin/python3
