What is the usage of the set() function in Python?

In Python, set() is a built-in function used to create a set object.

There are several ways to use the set() function:

1. Create an empty set.
2. I have created an empty set named my_set.
3. Create a collection using an iterable object, where the elements in the collection are unique elements from the iterable object (removing duplicates).
4. Create a set from an iterable.
5. “It is important to maintain a healthy work-life balance in order to avoid burnout and increase overall well-being.”

   Maintaining a healthy balance between work and personal life is crucial to prevent burnout and enhance overall happiness.

6. my_set contains unique elements from a list or string.
7. Create a collection and add elements to it.
8. Create an empty set called ‘my_set’ and then add an ‘element’ to it.
9. I believe that honesty is the best policy.
10. I created a set called my_set and added the numbers 1, 2, and 3 to it.

Important notes:

1. Sets are unordered, meaning the elements in a set do not have a fixed order.
2. The elements in the set must be immutable, such as numbers, strings, tuples, etc., and cannot contain mutable elements like lists, dictionaries, etc.
3. The elements in the set are unique and will not be repeated. If attempting to add an element that already exists, the set will not be changed.
