Introduction To Python SET Data Type

• SET is the collection of unordered, unchangeable and unindexable items
• SET is the mutable data type, because we can add or remove items from set
• But set elements are immutable because we cannot change item after creation but can add more items.
• SET element stored in curly braces {}.
• Every element / items separated by comma.
• SET can contain only immutable data type element like integer, string etc
• When we store mutable data type like list, it will return TypeError exception.
• SET can be created using set() method.
• It take iterable object as argument
• It store unique elements
• It remove duplicated elements / items
• We can create empty set? using set() method

Real world SET Examples

• School Bags
• Playlist
• Kitchen
• Dinner set

Modification of Element in SET

• We cannot modify an element of a set..
• We can add a element using the add() method
• To add multiple items, we use update() method.
• It take tuples, lists, strings or other sets as argument.

Duplication of Element in SET

• A set cannot contain duplicate items.
• Set() method remove automatically duplicate elements.
