In addition to David's pointers to code using combinations, here's a
one-liner based on more_itertools. Given combinatoric explosion,
it might be better to use a genexp instead of a list as return value,
and an "efficient but convoluted" algorithm might be justified if
len(s) is at all large.
# more_itertools is not in stdlib, but can be pip'ed
from more_itertools import partitions as p
def segment(s, m):
return [tuple("".join(y) for y in x) for x in p(s) if len(x) == m]
