When to use a dectionary or a list
Lists retain order while dictionaries do not, hence time ordered data should only be used with lists. Dictionaries associate unique hashable keys with values, membership tests are also much faster with dictionaries (foo in bar). Lists allow for arithmetic operations much more readily than lists do (sum(), avg())
