def simpleDecode(ciphertext, alphabet, cipher): """ Given ciphertext to decode, an alphabet and a cipher alphabet, return the decoded plaintext. If the lengths of the alphabet and cipher are not the same, return -1. If a character from ciphertext is not found in the cipher alphabet, return None. """ return "stub"

Note:

In the directions for the simpleDecode() function, it was stated that your function should return None if a ciphertext character does not exist in the alphabet. What we meant to say was that if a ciphertext character does not exist in your cipher alphabet, then return None. The reasoning for this is that if you cannot find a ciphertext character in your cipher, then there is no way to decode the ciphertext. This might be why some of you were facing difficulty with passing test_simpleDecode_3(). We will be testing your code with different alphabets and ciphers.
