Answer 1

Here is a one line solution:

>>> from itertools import chain, permutations
>>> print(*chain(*(map("".join, permutations(data, i)) for i in range(1, 3))), sep="\n")
BBBB
AAAA
CCCC
BBBBAAAA
BBBBCCCC
AAAABBBB
AAAACCCC
CCCCBBBB
CCCCAAAA

Answer 2

This code might help you out,

from itertools import permutations as per
input_nos = int(input('the number of strings')) #for specifying the input iterations
strings = []
for i in range(input_nos):
 strings.append(input())
strings_per = per(strings, input_nos -1 ) # as specified
for i in strings_per:
 print(''.join(i))

Answer 3

strings_list = ['AAAA', 'BBBB', 'CCCC', 'DDDD', 'EEEE']
def permute_string(a):
 b = []
 b.extend(a)
 for i in range(len(a)-1):
 for j in range(i+1, len(a)):
 b.append(a[i] + a[j])
 return b
permute_string(strings_list)

Based on what information you have give, this should do your work.
