COMMENTS: Comments are useful for documenting what your code and program does.

Comments begin with a # symbol and appear gray in the editor. Anything after # is ignored by the computer!

• Oops, this whole program is commented! Some of these lines are explanations and should be code, but not all!
• Uncomment the right lines of code by deleting the # or check out the tip below to make the program run correctly.
• TIP: Try highlighting code and using Ctrl + / on your keyboard to comment or uncomment code!
