Solution to the "SyntaxError: Invalid Character in Identifier" you might get from the color_mapper code. [Feedback]

While trying to use the color_mapper code I got a "SyntaxError: Invalid Character in Identifier" error. I'm doing this course in a Jupyter Notebook so I'm not sure this will happen in other IDEs. When you copy and paste the code you get

color_mapper = CategoricalColorMapper(factors=[‘Asia’, ‘Africa’, ‘Antarctica’, ‘Australia’, ‘Central America’, ‘Europe’, ‘North America’, “Oceania’, ‘South America’], palette=[‘#00FF00’, ‘#FFD343’, ‘darkgray’, ‘brown’, ‘cyan’, ‘crimson’, ‘red’, ‘#0000FF’, ‘purple’])

and you can see that syntax coloring goes wonky part way through, which along with the error told me there is a character being misinterpreted. I checked for non-printable characters with repr() and to see if any of the color codes need to be escaped out for some reason. Eventually, I noticed that the issue seems to be curly ‘’ vs straight '' quotes.

I threw it in Sublime to find and replace all curlys with straights and got

color_mapper = CategoricalColorMapper(factors=['Asia', 'Africa', 'Antarctica', 'Australia', 'Central America', 'Europe', 'North America', 'Oceania', 'South America'], palette=['#00FF00', '#FFD343', 'darkgray', 'brown', 'cyan', 'crimson', 'red', '#0000FF', 'purple'])

Which makes the syntax coloring happy and resolves the error.
