- update() is a python function which is update or add new items in the given set.

Syntax-

-Here list shows the items whicbh are add on the set.

Example

set.update([4]) will give {1,2,3,4}


program-

s=set([1,2,3])
print("Set is ",s)

s.update([4])
print("Set is",s)

s.update([5,6,"one","two"])
print("Now set is",s)

output-

Set is {1, 2, 3}
Set is {1, 2, 3, 4}
Now set is {1, 2, 3, 4, 5, 6, 'one', 'two'}

-In this program, we have a set {1,2,3} then firstly we pass [4] in update so set become {1,2,3,4}, then further we pass a list [5,6,"one","two"] in update() function so set is finially become {1, 2, 3, 4, 5, 6, 'one', 'two'}.
