  • Difficulty Level : Medium
  • Last Updated : 04 Sep, 2018

The set add() method adds a given element to a set if the element is not present in the set.

Syntax:

set.add(elem)
The add() method doesn't add an element to the
set if it's already present in it otherwise it 
will get added to the set.
Parameters:
add() takes single parameter(elem) which needs to 
be added in the set.
Returns:
The add() method doesn't return any value.




# set of letters
GEEK = {'g', 'e', 'k'}
  
# adding 's'
GEEK.add('s')
print('Letters are:', GEEK)
  
# adding 's' again
GEEK.add('s')
print('Letters are:', GEEK)

Output:

('Letters are:', set(['k', 'e', 's', 'g']))
('Letters are:', set(['k', 'e', 's', 'g'])

Application:

# set of letters
GEEK = {6, 0, 4}
  
# adding 1
GEEK.add(1)
print('Letters are:', GEEK)
  
# adding 0 
GEEK.add(0)
print('Letters are:', GEEK)

Output:

('Letters are:', set([0, 1, 4, 6]))
('Letters are:', set([0, 1, 4, 6]))
