Question

Suppose I have 4 words, as a string.
How do I join them all like this?

s = orange apple grapes pear

The result would be a String:

"orangeapple/orangegrapes/orangepear/applegrapes/applepear/grapespear/orangeapplegrapes/orangeapplepear/applegrapespear"

I am thinking:

list_words = s.split(' ')
for l in list_words:

And then use enumerate? Is that what you would use to do this function?

Answer 1

Maybe this is what you want?

s = "orange apple grapes pear"

from itertools import product
l = s.split()
r='/'.join(''.join(k*v for k,v in zip(l, x))
           for x in product(range(2), repeat=len(l))
           if sum(x) > 1)
print r

If run on ‘a b c’ (for clarity) the result is:

bc/ac/ab/abc
