IndentationError: unindent does not match any outer indentation level

The Short Explanation:
Open your app folder and edit your code in Sublime Text from now on to avoid indentation errors.

**Head to the Downloads section of Sublime Text and download the most recent version

The Longer One:
If after finding your code is entered in exactly as the teacher types it, indents in line, no extra spaces… Well. Last but not least, check your editor.

If you are using an editor that is NOT Sublime Text (Version 2 at the time of this blog post, Aug 2016), well then, your editor may be using spaces instead of REAL tabs, throwing an error.

This means to our human eye, the code is correct! But Python knows better and can pick out any phony editor’s space substitutions for tabs any day.

Notepad and TextWrangler have failed us in this field, reportedly.

I had an issue with this error on this lesson:
