Keeping this open, because it's referenced on the site.

This is a great idea! Thanks for sharing.

Do you know of other efforts in higher education that have taken the same approach as you have?

You teach high school programming and also college level programming? Also, your Gratipay "contribute" option is "outdated" :) Perhaps other ways of hooking you up and saying "Thanks!" ?

This is from introtopython.org, dictionary page and the last example code for "Looping through all values in a dictionary",

The user is supposed to input, but an input line is not written in the code.

p.s. Thanks for the amazing website.

I haven't touched this project in 6 years. I don't have specific plans to take it down, but I'm also not likely to update it anytime soon.

I'm glad to hear it still works well for people, though. :)
