Python set() Function: Uses & Examples

In Python, the set() function is used to create an unordered and unique set. Sets are a data structure similar to lists, but with non-repeating elements. You can use the set() function to convert other iterable objects (such as lists, tuples) into sets, or create an empty set using a pair of empty curly braces {}. Since sets are unordered, elements cannot be accessed by index, but operations like intersection, union, and difference can be performed using set methods.
