[Tutor] Dictionaries

[Lloyd Kvam]

If I understodd properly, you could replace:
	{1: a,b,c,d,e,f,g,h,i}
with
	{1: [a,b,c,d,e,f,g,h,i]}

The square brackets are used to represnt a list. Parentheses are used to 
denote a tuple.  The parentheses will sometimes be assumed as in your 
case.  a,b,c == (a,b,c).

Lists are mutable, tuples are not mutable.

dict[1][2] = C will replace c with C in your first list.
