Data Structures - Sequence
This post includes notes on linear data structures.
List and C,R,U,D of list
List has values in sequence. Implicitly, it also has length (or size) for list and indices (for elements) properties. In brief,
val = list [index] and
length = len(list).
Creating a list by initializer
a = 
R: Read: get val from index, get length of list, or, get index from val
Index => val
pop() removes and returns the last item in the list.
