I was solving the itertools.permutations() code on Hackerrank at https://www.hackerrank.com/challenges/itertools-permutations/problem and I came up with the following very simple code:
from itertools import permutations
to_perm, length = raw_input().split()
length = int(length)
res = permutations(to_perm, length)
new_res = []
for i in res:
new_res = sorted(res)
for i in new_res:
print "".join(i)
This is what I get as output:
AC
AH
AK
CA
CH
CK
HC
HK
KA
KC
KH
And this is my expected output:
AC
AH
AK
CA
CH
CK
HA
HC
HK
KA
KC
KH
You'll notice that I'm missing the permutation 'HA'.
My question is : Why am I missing this single permutation? And how can I solve this?

I'm not sure what happens to HA in your code. This code outputs the correct result:
from itertools import permutations
to_perm, length = 'HACK', 2
res = permutations(to_perm, length)
res = sorted(res)
for perm in res:
print ''.join(perm)
Outputs
AC
