Can any one clarify what "while stack:" mean?
By convention, an empty container is considered false and a non-empty
container true in Boolean tests.
Therefore, assuming that "stack" is a container, it means "while the
stack isn't empty".

It iterates as long as 'stack' has something that evaluates as true.
My guess is that stack is a list, and the loop is removing elements
from that list, so it'll keep going as long as there's anything
