Set definition:

A set (set) is an unordered sequence of non-repeating elements .

Creation:

You can use curly brackets { } or the set() function to create a collection.

Note: To create an empty collection, you must use set() instead of { }, because { } is used to create an empty dictionary.

Format:

parame = {value01,value02,...}

or

set(value)

Example:

jihe = {1,2,3,4,5} #与字典看上去类似，但是是不一样的。字典是 dict1 = {key:value,key2:value2,}需要key

Add elements:

Use set.add() Method

Example:

set1 = {1,3} set1.add(2)print(set1)
