Answer 1

Set

A set is a collection which is unordered and unindexed, and doesnt allow duplicates. In Python, sets are written with curly brackets.

# example set
newset = {"one", "two", "three"}

• You cannot access items in a set by referring to an index
• Sets are mutable
• They are useful for checking for duplicates

List

A list is a collection which is ordered and changeable. In Python lists are written with square brackets.

# example list
newlist =["one", "two", "three"]

• You access the list items by referring to the index number
• Lists are mutable.
