There are 36 possible combinations of two dice.
A simple pair of loops over range(6)+1 will enumerate all combinations.
The sum of the two dice is more interesting than the actual combination.
Create a dict of all combinations, using the sum of the two dice as the key.

Each value in the dict should be a list of tuples; each tuple has the value of two dice.
The general outline is something like the following:

d= {}
Loop with d1 from 1 to 6
Loop with d2 from 1 to 6
newTuple ← ( d1, d2 ) # create the tuple
oldList ← dictionary entry for sum d1+d2
newList ← oldList + newTuple
replace entry in dictionary with newList

Loop over all values in the dictionary
print the key and the length of the list
