List Definition in Python
Python List: List is a collection of data of different data type. It is used to store list of values. A list is created by putting list of comma-separated values between square brackets. A list in Python is an ordered, mutable (changeable) collection of items. Lists can store elements of different data types. List is a collection which is ordered and changeable. List is a allows duplicate members.
List All Functions in Python
