In this article, we would like to show you how to remove set items in Python.

Quick solution:

my_set.remove('item')

or

my_set.discard('item')

Note:

The difference between remove() and discard() method is that when the item to remove doesn't exist, the discard() method won't throw an error.

 

1. Practical example using remove() method

In this example, we use remove() method to remove B item from the set.

my_set = {'A', 'B', 'C'}

my_set.remove('B')

print(my_set)  # {'C', 'A'}

Output:

{'C', 'A'}

2. Using discard() method

In this example, we use discard() method to remove B item from the set.

my_set = {'A', 'B', 'C'}

my_set.discard('B')

print(my_set)  # {'C', 'A'}

Output:

{'A', 'C'}

3. Clear the set

In this example, we use clear() method to empty the set.

my_set = {'A', 'B', 'C'}

my_set.clear()

print(my_set)  # set()

Output:

set()
