List in Python
The simplest data structure in Python and is used to store a list of values.
Lists are collections of items (strings, integers, or even other lists).
Each item in the list has an assigned index value.
Lists are enclosed in [ ]
Each item in a list is separated by a comma
Unlike strings, lists are mutable, which means they can be changed.
Examples:
emptyList = [ ]
list1 = [‘one, two, three, four, five’]
numlist = [1, 3, 5, 7, 9]
mixlist = [‘yellow’, ‘red’, ‘blue’, ‘green’, ‘black’]
An empty list is created using just square brackets:
list = []
