Associating tuple values to a dictionary key and subsequent values

[GTXY20]

Have a little bit of a problem:

I have the following dictionaries:

d={'1': ['a', 'b', 'c', 'd'], '3': ['a', 'b', 'c', 'd'], '2': ['a', 'b', 'c', 'd'], '4': ['a', 'c']}
update={'a': 10, 'c': 4, 'b': 5, 'd': 1}

I use the following to output:

Combqtyoutfile = open('Combqty.txt', 'w')
    Combqtyoutfile.write('Qty\tNumber\tCombination\n')
    from collections import defaultdict
    fcomb=defaultdict(int)
    for v in d.values():
        fcomb[tuple(v)]+=1
    for count, items in sorted( ((v,k) for k,v in fcomb.items()),reverse=True):
        comb=','.join(items)
        hnum = len(items)
        Combqtyoutfile.write ('%s\t%s\t%s\n' % (count,hnum,comb))
    Combqtyoutfile.close()

this outputs to my text file:

QTY Number Combination
3 4 a,b,c,d
1 2 a,c

What I want to do is also include sum of values associated with elements in the combination based on the dictionary 'update' so that my file would then read:

QTY Number Combination Sum
3 4 a,b,c,d 20
1 2 a,c 14

Just wondering how I can associate the update dictionary in the for loop where the combination counts are determined.

Any advice is greatley appreciated.

Thanks in advance.

I did not understand your question at first.

>>> update={'a': 10, 'c': 4, 'b': 5, 'd': 1}
>>> d={'1': ['a', 'b', 'c', 'd'], '3': ['a', 'b', 'c', 'd'], '2': ['a', 'b', 'c', 'd'], '4': ['a', 'c']}
>>> for key in d:
...     summation = sum([update[s] for s in d[key]])
...     print summation
...     
20
20
20
14
