.clear()

In Python, the .clear() method removes all elements from a set, resulting in an empty set. This method does not return any value.

Note: The .clear() method performs the operation in-place, modifying the original set rather than creating a new one.

Syntax

set_object.clear()

• set_object: The set from which all elements will be removed.

Example

In the example below, the .clear() method is used to remove all elements from the pets set, leaving it empty:

pets = {"cats", "dogs", "hamsters", "lizards", "turtles"}
print("Original set:", pets)

pets.clear()
print("After calling clear() on pets:", pets)

The resulting output will look like this:

Original set: {'hamsters', 'dogs', 'turtles', 'cats', 'lizards'}
After calling clear() on pets: set()

Note: A set in Python is unordered. That’s why the order of items in Original set may appear different in the above output.
