Will the changes I made (file and dir removals from os.walk()) be reflected in the generator object? Is it safe to remove objects this way and pass the results in a generator on to another function? Sorry for all the questions, I just like to fully understand something before I start doing it with confidence.
Yes. The docs for os.walk() explicitly state, "When topdown is true, the caller can modify the dirnames list in-place (perhaps using del or slice assignment), and walk() will only recurse into the subdirectories whose names remain in dirnames."
So changes to the dir list affect the iteration; changes to the file list directly affect the value you return to the caller.
