A deciphering problem

[ibreeden]

I see no obvious logic in the 7 keys as a sequence or so.

Of course there is a logic: it is to stimulate you to decode it with a program, not by hand!

The first line key = 32

Note that Truman subtracts so his result is len(SYMBOLS) - 32 = 34. With that method one would get:

Output:
KEY  TEXT
 34  I love my kitty,
 44  My kitty loves me,
  7  Together we're happy as can be,
 32  Though my head has suspicions,
 45  That I keep under my hat,
 11  Of what if I shrank to the size of a rat.
  1  Yeah, she would probably eat me.

The question is, did you get the solution beforehand,
as part of the exercise?
Because then you can calculate the offset(s),
without having to revert to trial and error,

That would not be "good sport", would it?

@Truman, I wrote another poem for you. Do you like it?
