Hands-On Data Structures and Algorithms with Python - Second Edition

Lists

List is one of the most commonly used built-in data structures, as they can store any number of different data types. They are simple representations of objects and are indexed by integers starting from zero, as we saw in the case of strings.

The following table contains the most commonly used list methods and their descriptions:

Method	Description
list(s)	Returns a list of sequence s.
s.append(x)	Appends element x at the end of list s.
s.extend(x)	Appends list x at the end of list s.
s.count(x)	Returns the count of the occurrence of x in list s.
s.index(x,[start],[stop])	Returns the smallest index i, where s[i]==x. We can include an optional start and stop index for the lookup.
s.insert(i,e) ...
