How multi-character substitution might explain the voynich’s strange entropy

[nablator]

I attach the function to cipher:

def homophonic_cipher_3c(words):
    letter_map = {c: [c + str(i) for i in range(3)] for c in 'abcdefghijklmnopqrstuvwxyz'}
    out = []
    for word in words:
        new_word = ''.join(random.choice(letter_map.get(c, [c])) for c in word)
        out.append(new_word)
    return out

It's a simple homophonic cipher. First creates a letter map for each alphabetical character (so, each letter will have three different letters to choose randomly during the cipher).

Thanks for the explanation. So the letter "l" is ciphered either as "l0", "l1" or "l2", only the digit is chosen randomly. This is not a homophonic cipher: the digits are all nulls.

Code:

import random def homophonic_cipher_3c(words):     letter_map = {c: [c + str(i) for i in range(3)] for c in 'abcdefghijklmnopqrstuvwxyz'}     out = []     for word in words:         new_word = ''.join(random.choice(letter_map.get(c, [c])) for c in word)         out.append(new_word)     return out pt = input('Enter plaintext: ') print(f'Ciphertext of plaintext "{pt}" is {homophonic_cipher_3c(pt)}')

Ciphertext of plaintext "tell me more" is ['t0', 'e2', 'l2', 'l0', ' ', 'm0', 'e2', ' ', 'm1', 'o1', 'r2', 'e1']
