How do i do this?

Question

def abstash_cipher(plaintext):
Ex) abstash_cipher(“abcd”) should be ‘zxyw’

its in python
Got to use a loop cannot use reverse

Answer 1

The first thing which comes to mind is using list operations.

def abstash_cipher(plaintext):
return ''.join([chr(ord(x)+25-((ord(x)-97)*2)) for x in list(plaintext.lower())])

print(abstash_cipher("abcdefghijk"))

This doesn't involve loops, but should give you a good idea of what to use, e.g. ord(), chr(), and the underlying conversion logic.

Ofc, if you want to simplify the equation, you can use:

return ''.join([chr(-ord(x)+219) for x in list(plaintext.lower())])

which is equivalent to the above.
