One of the most useful (to me) structures is the double-ended queue ("from collections import deque”).  It creates a queue that can quickly remove an item from one end and add an item to the other.  Particularly useful for displaying a sliding window into time series data, or a moving track of the most recent n observations of a physical measurement.
