LIST
In Python, a list is a type of container that is used to store a list of values of any type. One can
store an integer, string as well as objects in a single list. Each element in a list is assigned an index
number. The first index is 0, the second index is 1, the third is 2, and so on.
CREATING A LIST
Lists can be created by inserting the elements in square brackets []. The elements in the list are
separated by a comma.
