Python Set add method with Example – Python Tutorial
6 years ago Lalit Bhagtani 0
In this tutorial, we will learn about python set add method.
add method :
This method is used to insert single immutable element ( passed as an argument ) in the set object. If we try to insert an element, which is already exist in the set object. It won’t insert that element again in the set. Element ( passed as an argument ) must be of immutable type like string, integer, float. If we try to insert a mutable type element like list, it will raises a TypeError.
Syntax : < Set Object >.add( < Immutable Object > )
Example:
# create empty set object and assign it to variable s
s = set()
# add element 1 in the set object
s.add(1)
# add element 2 in the set object
s.add(2)
# print all elements of set
print(s)
# add element 2 in the set object
s.add(2)
# print all elements of set
print(s)
# element 2 is not added second time
# add list [1,2,3] in the set object
s.add([1,2,3])
# TypeError is raised as list is not immutable type
