Morsecode generator implementation, converts unicode strings from/to morsecode.

morse.py

from itertools import zip_longest
from functools import partial

def grouper(iterable, n, fillvalue=None):
  args = [iter(iterable)] * n
  return zip_longest(*args, fillvalue=fillvalue)

def morsedec(s, bits=8, chars='.-') -> str:
  return ''.join(chr(int(''.join(b), base=2)) for b in
    grouper(map(lambda b: str(chars.index(b)), s), bits, '0'))

def morseenc(s, bits=8, chars='.-') -> str:
  return ''.join(map(lambda c: ''.join(map(lambda b: chars[int(b, base=2)],
    '{:b}'.format(ord(c)).rjust(bits, '0'))), s))

I'm aware that the code quality is horrible but it works!
