Python Itertools.Permutations()

Question

Why does itertools.permutations() return a list of characters or digits for each permutation, instead of just returning a string?

For example:

>&g         


        

Answer 1

Because it expects an iterable as a parameter and doesn't know, it's a string. The parameter is described in the docs.
