I don't understand the "category" choices in options.items()? I'm sure we went over this way back when

options is a dict called DEFAULTS what is .items() doing ? where did category come from, was this just arbitrary

1 Answer

for category, choices in options.items()

This is using tuple assignment. dict.items() returns an iterable of tuples to loop over comprised of (key, value) pairs. The dual assignment allows you to retrieve the key and the value to use in the loop.

So essentially its going to take DEFAULTS as it was loaded into the view as options

options.items() gives us an iterable of tuples that gets assigned (category, choice) for (key, value)???

That is correct.
