How to create an Empty Set in Python ?

Answer

To create an empty set in Python, you can use either the set() constructor or the curly braces {} notation.

✐ Examples

1 Create Empty Set using set() Constructor

In this example,

We use the set() constructor to create an empty set in Python.
This function initializes an empty set ready to store unique elements.
We can perform set operations such as adding elements, removing elements, and checking for membership on the empty set.

Python Program

# Create an empty set using set() constructor
empty_set = set()

# empty_set is now ready to be used as an empty set

# Example usage:
# Add elements to the set
empty_set.add(5)

# Remove elements from the set
empty_set.remove(5)

# Check if an element is present in the set
contains_element = 5 in empty_set

print(f'Is element 5 present in the set: {contains_element}')

Output

Is element 5 present in the set: False

2 Create Empty Set using Curly Braces

In this example,

We can also create an empty set in Python using the curly braces {} notation.
This method provides a more concise way to create an empty set compared to using the set() constructor.
We can manipulate the empty set using set operations such as adding elements, removing elements, and checking for membership.

Python Program

# Create an empty set using curly braces
another_empty_set = {}

# another_empty_set is now ready to be used as an empty set

# Example usage:
# Add elements to the set
another_empty_set.add('apple')

# Remove elements from the set (if it exists)
another_empty_set.discard('apple')

# Check if an element is present in the set
contains_element = 'apple' in another_empty_set

print(f'Is element 'apple' present in the set: {contains_element}')

Output

Is element 'apple' present in the set: False
