Question

test = ["a","b","c","d","e"]

def xuniqueCombinations(items, n):
    if n==0: yield []
    else:
        for i in xrange(len(items)-n+1):
            for cc in xuniqueCombinations(items[i+1:],n-1):
                yield [items[i]]+cc

x = xuniqueCombinations(test, 3)
print x

outputs

"generator object xuniqueCombinations at 0x020EBFA8"

I want to see all the combinations that it found. How can i do that?

Answer 1

leoluk is right, you need to iterate over it. But here’s the correct syntax:

combos = xuniqueCombinations(test, 3)
for x in combos:
    print x

Alternatively, you can convert it to a list first:

combos = list(xuniqueCombinations(test, 3))
print combos
