python - Permutation of x length of 2 characters

Question

Lets say I have two characters: a & b. I want to get a list of all possible permutations of a and b for a given length (i.e. 5), using Python 2.7.

I have looked at itertools.permutations, but was unable to find a way that allowed me to use 2 characters to build a permutation longer than 2 characters.

I have also looked at multiple SO answers for Python permutations, such as this one, but this, along with the others, will only give permutations of len(input) length.

Also, if there is a good way to do this using a different programming language, please suggest it. I am not set in stone on using Python for this.

Answer 1

That way:

import itertools
x = ['a','b']
print [p for p in itertools.product(x, repeat=5)]
