Lists

Lists in Python are equivalent to structures as dynamic vectors in programming languages such as C. We can express literals by enclosing their elements between a pair of brackets and separating them with commas. The first element of a list has index 0. The indexing operator allows access to an element and is expressed syntactically by adding its index in brackets to the list, list [index].

Consider the following example: a programmer can construct a list by appending items using the append() method, print the items, and then sort them before printing again. In the following example, we define a list of protocols and use the main methods of a Python list as append, index, and remove:

>>> protocolList = []>>> protocolList.append("ftp") ...
