OK, I have now read your discussion with Kent.
Can i ask, have you tried going through any of the basic tutorials?
They all cover this kind of stuff, especially dictionaries and
raw input and string concatenation etc. It will be much more
effective to work through a tutorial than to keep coming back
here with every little question. Try the Raw Materials topic of
my tutorial for starters. It gives an example of a phone book
comprised of a list stored in a dictionary keyed by name...
However as to this question, you can store any Python
object as the value of a dictionary (even another dictionary),
and you can use any *immutable* object as a key.
So if I want to store two numbers as a value against another
two numbers you can just do this:
mapping = { (1,2):(10,20), (3,4): (30,40) }
print mapping[(1,2)] #-> (10,20)
mapping[(5,6)] = (50,60) # assign new value
