# Print all permutations formed by concatenating every word in a 
# list with every other word in the same list. Good for generating 
# idea/project/company names from a list of relevant words. The list
# will be sorted by word length.

from itertools import permutations
words = "spam eggs beans".split()
perms = ["".join(permutation) for permutation in permutations(words, 2)]
print "\n".join(sorted(perms, lambda a, b: len(a) - len(b)))

# Outputs:

# spameggs
# eggsspam
# spambeans
# eggsbeans
# beansspam
