Don't see value of and condition here. If targetLink == link it will always be targetLink, right?

I want to make sure targetLink since Python is a dynamic language, it's impossible to tell ahead of time what items a list may contain. If a None were to somehow get inserted, I don't want it to return a false positive.

Good catch, didn't think about that. I'm going to just put a try-except block and just pass errors. If there are errors, then we can just assume the link isn't valid.

Issue #102
Changes Proposed
Explanation of Changes
Two functions have been added, one which accepts the html of a webpage and an integer which represents the depth at which to stop. This function invokes the traversal function which searches the links using Breadth First Search algorithm.
