Lists in Python represent ordered sets of elements with finite length. In a list, elements with same value can occur multiple times. Lists are a type of mutable sequences in Python, as any element can be added to or removed from a list.
As with any sequence, the elements in the lists are identified with an index ranging from 0 to length-1 of the list. Slicing operations are supported in lists and they produce new lists or sequences which are subsets of the original list.
