hello....why does it resolves to a "ko", i was thinking "ko" is a Failure; why does it returns a success("ko"), probably am not getting it; if you can please...

Because transform changes it into Try("KO"), which is a success because no exception is thrown.

I don't know why I don't get it....can you elaborate on what the point is , if it returns the other failure instance . How does that apply to normal things to solve future problems.....if there is a possibility of getting something different from what I Try[T]-ied for success, then why should I use this....I don't understand.. help me pls.

The forecast example from this post should answer your question.
