Hint: Use IntegerDigits, Map and Style.

Due to popular demand, a Q&A digest is being compiled throughout the week, and this is posted along with the other Study Group materials at the download location. Check your Study Group reminder and recording notification emails for that link. The Q&A digest for Days 1 and 2 is now available.

Hi! We're actually putting the finishing touches on a Parallel Programming video class right now :). It should be ready quite soon!

One more note, for now: some students requested that the poll questions be made available because of timezone issues preventing them from taking the polls/watching the lectures in real-time. I've added a notebook with the poll questions (answers bolded) to the downloads folder.

Hi Mitch—the abbreviated form is what I stated above. Are you looking for a way to convert what you've written into that abbreviated form? If so, I'm not sure that there's a "native" way to do that, but you also shouldn't need to do that because these are functions that you write from scratch anyway, so you would just choose the format you wanted when writing them for the first time.

Here's a hacky solution that I've come up with; I can't guarantee that it works in 100% of cases: converter[func_] := (Evaluate[func[[2]] /. func[[1]] -> #]) & It extracts the "function" part of the Function, then replaces the "variable" part with a Slot[1] (#). The "Evaluate" is to make this operation actually evaluate, because by default it's taking the right-hand side as a pure function per se and thus not evaluating it. Then, I put a & at the end of this replaced version to close off the newly-made pure anonymous function.

# represents an arbitrary input without making explicit reference to a dummy variable like u or x. Except for in some very particular edge cases where you're nesting pure anonymous functions and can get into ambiguities about which slot is being referred to, it is exactly the same as Function[u,3+u] (which is also equal to Function[3+#]).

Do you have some particular use case in mind where these are not equivalent? If so, could you provide some more information?

Hi Mitch! You're looking for:

3+#&[x]

The # represents the slot into which an input will go (analogous to a what a variable in a function does) and the & closes it off. At that point, the whole construct 3+#& acts like any other function f.

I am intrigued but confused by RemoteBatch.

Could Wolfram U consider offering some courses?
