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(calendar.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. :-)
