# Error 1: mixing tabs and spaces.
# I used the tab key to intend all commands in this function except the last one.
# I hit the spacebar (space) 4 times to intent the last line.
# Tabs and spaces are both considered "whitespace".
# Results in: IndentationError: unindent does not match any outer indentation level
#
# Fix 1: Manually delete one of the whitespace and change it to the other one.
# Fix 2: In VS Code: click "Spaces:" on the bottom-right of VS Code, click on 
# Convert Indentation to Spaces.
# VS Code then will convert all indented lines to spaces (as would be produced by
# pressing spacebar)!
#
# I suggest using spaces to indent rather than tabs, but either work fine.
# Pick one and stick with it!
