I need a string/list/generator/comprehension incantation.

[Steven W. Orr]

I really tried. I give up.

I got this one last time (for which I'm very grateful).

import calendar
months = dict([(month,ii) for ii,month in enumerate(calen dar.month_abbr)][1:])

Now I want something that's going to give me a string whose value is the
set of all of the first letters of months. Order is not important.

And for extra credit, I need the string whose value is the set of all of
the letters of months minus the first letter.

E.g., 'ADFJMONS', 'acbeglonprutvy '

Thanks in advance to all the wizards out there. :-)

"".join(set (m[0] for m in calendar.month_ abbr[1:]))

"".join(set("". join(m[1:] for m in calendar.month_ abbr[1:])))

Those are the ways that are obvious to me anyway, maybe there are
better ways. If you actually want a set not a string, remove the
outer-most "".join().

Boy am I sorry we did your homework for you. If you have no idea where
to go, and you can't even show your work, you need to see a TA or
instructor. You are already in over your head; back up and learn to
swim.
