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

Perumatation can be done for strings and list also, below is the example..

x = [1,2,3]

if you need to do permutation the above list

print(list(itertools.permutations(x, 2)))

# the above code will give the below..
# [(1,2),(1,3),(2,1)(2,3),(3,1),(3,2)]
