Python Set clear() Method

The clear() method removes all elements from a set, leaving it empty.

Syntax

set.clear()

Parameters

No parameters.

Return Value

Doesn’t return any value (returns None). It modifies the set in-place.

Example:

fruits = {"apple", "banana", "mango", "orange"}
print(fruits) # Output: {'apple', 'mango', 'banana', 'orange'}

# Clear the set
fruits.clear()
print(fruits) # Output: set()

Python sets are unordered, so the elements may appear in a different order each time you print them.

Also note that an empty set is written as set(). The notation {} indicates an empty dictionary, not an empty set.
