Ghost objects are given a random color **attribute** Your code is writing a method for the Ghost class.

Agreed! Messed up at first because I reversed it without noticing I wasn't supposed to.

Seems like a nice kata will take so time tho ^^

They are good I got around 10-15 of them :) not more ^^

Ty, I total forgot that... I was confused when I saw it on Rosalind(I even learned about it)... but I guess I have forgotten :(. I will put it in description. I can't change now since all of the solutions will be false. I will make them for sure :) maybe one will come tomorrow :). I'm very busy at the momment :)

I knew that, but preferred to respect the author's original inclination. As I stated, I would like to bring some problem from Rosalind to CW, both because bioinformatics surely are challenging and also because I really like the field.

Thanks for your feed, though :)
