pylist

"""
Lists are used to store multiple items in a single variable.

Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set,
and Dictionary, all with different qualities and usage.

"""

Lists are created using square brackets

thisList = ["apple", "banana", "cherry"]
print(thisList)

'''
List items are ordered, changeable, and allow duplicate values.
List items are indexed, the first item has index [0], the second item has index [1] etc.
Ordered: When we say that lists are ordered, it means that the items have a defined order,it same with the order that we
put the iterm into the list.If you add new items to a list, the new items will be placed at the end of the list.
Changeable:The list is changeable, meaning that we can change,add,and remove items in a list after it has been created.
Allow Duplicates:Since lists are indexed, lists can have items with the same value:

'''

dupList = ["apple", "banana", "cherry", "apple", "cherry"]
print(dupList)
