[Tutor] Looping over histogram plots

[Elaina Ann Hyde]

Dear Don,
    Thanks for the comment, the set type is no problem for me, this is just
a variable that I call set... and it works great for my purposes, I do
suspect it is something in the way that matplotlib/pyplot deals with
histograms, but I have not so far been able to find the right syntax.
 Note, the first code example works great, it is only the second (with the
hist attempt) that does not do well.  It creates 29 blank plots and 1
histogram instead of 30 histograms... so probably it does need a different
phrasing, but the one you suggest gives invalid syntax.
