I am also facing the maketrans issue.

thanks!

It works now! cheers.

Can it be because of a dict copy?

(python) I am passing the first 10 tests (all unique letters and all duplicate ones). Yet, on the random ones the first one is always yelling:
Traceback: in
in permsol
TypeError: argument 2 to map() must support iteration
I am not using itertools. Any clue? thanks.

Interesting kata! typo for Specifity

I'd rather maintain something like this than a regex. I mean, python is supposed to be about readibility, no? Thanks for this clean solution anyway.

Yes, I understood why it was dry. But having to redo other kata when this one is relatively simple for a 6-5 can be felt like time consuming? I don't know.
Just a little something that would make me understand immediately (but it's your kata ;):
xbonacci(signature, nth)
signature is the start of the sequence, its length also determines which Xbonacci you are playing with ([0,1] -> 2 -> fibonacci, [0,0,1] -> 3 -> tribonaci...)
nth is the expected length of your return sequence

Simple and fresh kata. Maybe the explanation should be a little bit more verbose, but I approve.
