This is really subtle, and is no doubt related to a copy-paste issue.
You have color=’blue’
. Notice how the quotes lean forward a bit. That is not a standard Python string delimiter; you need normal (ASCII) single or double quotes. Here you can see what you get if you use color='blue'
as correct.
Looks good otherwise! Welcome to Sage! I'll put some other comments in the, well, comments.
