Hi, All. Crave pardon if that question of mine was too basic to merit a reply, but I couldn't find anything by searching. Newbie Python user here. I finally did find the answer and thought I'd post it in case someone might come along with the same question. The problem is with the way I was us

[Tutor] deriving class from file to handle input line numbers?
