Enigma Machine, I need help!

[Larz60+]

After all this time, this is kind of a cop out, but one with a solution.
I certainly did learn a lot about the enigma machine during the process.

As it turns out, there was already an enigma cipher/decipher algorithm available.
So here's a synopsis on how to use it:

• Install package pycipher with

  pip install git+git://github.com/jameslyons/pycipher

• Set up and use as in sample below (which contains an alpha to num and num to alpha functions for
     help in conversion of ringstellung and window settings.
  

This returns the proper code 'GVYWHF' for 'ENIGMA'
when

window = 'Q', 'u', 'O' (left to rih=ght)
rotors =  V, III, and I (left to right)
plugboard = M <--> Z and N <--> S
Rings set to 12, 4, 8 ('L', 'D', 'H')
Reflector = 'B'

import pycipher
import string


def num_to_letter(nums):
   """
   Convert number of alphabet to characters
   :param nums: list of numbers, 1 based
   :return: list of letters
   """
   alpha = string.ascii_uppercase
   alst = []
   for num in nums:
       alst.append(alpha[num - 1])
   return alst

def letter_to_num(letters):
   """
   Convert letters of alphabet to numbers
   :param letters: list of letters
   :return: list of numbers, 1 based
   """
   alpha = string.ascii_uppercase
   nlst = [ ]
   for letter in letters:
       nlst.append(alpha.index(letter) + 1)
   return nlst

if __name__ == '__main__':
   se = pycip = pycipher.Enigma(settings=('Q', 'U', 'O'),
                           rotors=(5, 3, 1),
                           reflector='B',
                           ringstellung=('L', 'D', 'H'),
                           steckers=[('M', 'Z'), ('N', 'S')])

   print(se.encipher('ENIGMA'))
   se.reset_settings()
   print(se.encipher('GVYWHF'))

Results:

Output:
GVYWHF
ENIGMA
