Example 1: Remove all elements from a Python set using clear()

# set of vowels
vowels = {'a', 'e', 'i', 'o', 'u'}
print('Vowels (before clear):', vowels)

# clearing vowels
vowels.clear()
print('Vowels (after clear):', vowels)

Output

Vowels (before clear): {'e', 'a', 'o', 'u', 'i'}
Vowels (after clear): set()
