[Tutor] Calculating and returning possible combinations of elements from a given set

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!
