Python .discard()

In Python, the .discard() method removes a specified element from a set. If the element is not found, it takes no action and does not raise an error either.

Syntax

set.discard(value)

• set: Refers to the set from which the specified element is to be removed.
• value: Denotes the element to be removed from the set.

Example

The below example shows the usage of the .discard() method:

coffee_set = {'espresso', 'flat_white', 'cappuccino', 'filter'}
print(coffee_set)

# Removing 'espresso' from the set
coffee_set.discard('espresso')
print(coffee_set)

# Removing 'latte' from the set
coffee_set.discard('latte')
print(coffee_set)

{'flat_white', 'cappuccino', 'filter'}
{'flat_white', 'cappuccino', 'filter'}

In the above example, the code continues to get executed without any errors despite the attempt to remove the element latte, which doesn’t even exist in the set.
