Join Two Sets

There are several ways to join two or more sets in Python.

You can use the union() method that returns a new set containing all items from both sets, or the update() method that inserts all the items from one set into another:

Example

The union() method returns a new set with all items from both sets:

set1 = {"a", "b" , "c"}

set2 = {1, 2, 3}

set3 = set1.union(set2)

print(set3)

Example

The update() method inserts the items in set2 into set1:

set1 = {"a", "b" , "c"}

set2 = {1, 2, 3}

set1.update(set2)

print(set1)
