Itertools are a core set of fast, memory efficient tools for creating iterators for efficient looping (read the documentation here). One (of many) uses for itertools is to create a permutations() ...
A recursive approach (which is what I would use) would involve breaking the problem into isomorphic subproblems: to find all permutations of a string, find all permutations of the string without a ...
