remove() return value

The remove() method only removes the given element from the set. It does not return any value.

Example1: Remove element from set

# language set
language = {'English', 'French', 'German'}
# Delete 'German'　
language.remove('German')
# Update language set
print('Updated language set: ', language)

The output when running the program is:

Updated language set: {'English', 'French'}

Example2: Try to delete a non-existent element

# animal set
animal = {'cat', 'dog', 'rabbit', 'pig'}
# Delete 'fish' element
animal.remove('fish')
# Update animal set
print('Update animal set: ', animal)

The following error will occur when running the program:

Traceback (most recent call last):
　　File '<stdin>', line　5, in <module>
　　　　animal.remove('fish')
KeyError: 'fish'

This is because the element 'fish' does not exist in the 'animal' set.

If you do not want to see this error, you can usediscard() method. If the element passed to the discard() method does not exist, the set remains unchanged.

A set is an unordered collection of elements. If you need to delete any element from the set, you can usepop() method.
