Hi all pythoners
I've got a probably easy to answer question.
Say I've got a collections of strings, e.g.: 'man', 'bat', 'super',
'ultra'.
They are in a list, or in a sequence or whatever, say a bag of words
And now I want to know how many couples I can do with them, and I want
the program to show me the actual couples: 'manman', 'manbat',
'mansuper', 'manultra', 'batbat', 'batman', 'batsuper', etc.
But hey, why building up new words from just two strings? I also want
to know the possible combinations of three words, four words, and
perhaps, why not, five words.
So, is it easy to do?
Sorry, I'm new in programing, and am probably far from being a math-master
I'm clueless, I think probably the code have some FOR I IN SEQUENCE...
but then what? I don't know how to say: take every element and paste
it to another one from the bag, and with another one, and with another
one,...
If it's too complex, I dont need the whole code recipe, just need some
clues, or perhaps a useful link
Thank you very much in advance!
Take a look in the itertools module
http://docs.python.org/library/itertools.html
Check the section "*Combinatoric generators:" (website doesn't have an
anchor link for that, search around a bit)
