there are many kinds of sequences, but they all share common behavior. In particular,

2.3 Sequences
ful, fundamental abstraction in computer science. Sequences are not instances of a particular built-in type or abstract data representation, but instead a collection of behaviors that are shared among several different types of data. That is, <span>there are many kinds of sequences, but they all share common behavior. In particular, Length. A sequence has a finite length. An empty sequence has length 0. Element selection. A sequence has an element corresponding to any non-negative integer index less than its length, starting at 0 for the first element. Python includes several native data types that are sequences, the most important of which is the list . 2.3.1 Lists A list value is a sequence that can have arbitrary lengt
