python encryption with a cipher

Question

I need to encrypt a string in python according to a cipher.

character_set = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 "
secret_key    = "Dd18Abz2EqNPW hYTOjBvtVlpXaH6msFUICg4o0KZwJeryQx3f9kSinRu5L7cGM"

any ideas? my function always returns a long list like:

code:

import string

def my_encryption(s):        
    s.translate(str.maketrans(character_set, secret_key))

in python 3 see https://docs.python.org/3/library/stdtypes.html#str.maketrans and https://docs.python.org/3/library/stdtypes.html#str.translate — Paweł Kordowski, Feb 28 '16 at 16:59

in python 2

>>> import string
>>> translate_table = string.maketrans(character_set, secret_key)
>>> string.translate("test", translate_table)
'BAjB'

in python 3:

>>> "test".translate(str.maketrans(character_set, secret_key))
'BAjB'

or manually in python 3:

>>> D = dict(zip(character_set, secret_key))
>>> ''.join(map(D.get, "test"))
'BAjB'

type str has no attr maketrans – Crashberry py Feb 28 '16 at 17:06
it has, https://docs.python.org/3/library/stdtypes.html#str.maketrans do you use python 3 or python 2? – Paweł Kordowski Feb 28 '16 at 17:07
python 3, but in edX, not a full python lib – Crashberry py Feb 28 '16 at 17:08
not really, and I guess you want to return something from your function, where do you define `character_set` and `secret_key`? I would like to see the whole code – Paweł Kordowski Feb 28 '16 at 17:14
character_set = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 " secret_key = "Dd18Abz2EqNPW hYTOjBvtVlpXaH6msFUICg4o0KZwJeryQx3f9kSinRu5L7cGM" – Crashberry py Feb 28 '16 at 17:15
I added a version not using `maketrans` – Paweł Kordowski Feb 28 '16 at 17:20
could you take a look at my other question at http://stackoverflow.com/questions/35678327/python-spell-checker ? – Crashberry py Feb 28 '16 at 20:17
