To create a set in Python, you can use curly braces {} or the built-in set() function. For example:
Sets are one of the 4 built-in data types in Python; it is an unordered collection data type that is iterable, mutable, and does not allow for duplicate elements.

To remove a specific element:
To clear all elements from the set:
