How to use the set function in Python?

In Python, a set object can be created using the set() function. The set() function takes an iterable object as a parameter and returns a set containing unique elements.

For example, you can use the set() function to create a set containing integers.

numbers = set([1, 2, 3, 4, 5])


{1, 2, 3, 4, 5}

In addition, you can also create a set containing strings using the set() function.

fruits = set(["apple", "banana", "orange"])


{'orange', 'apple', 'banana'}

Please note that the set() function creates a collection that is unordered and does not contain duplicate elements. If there are duplicate elements in the iterable object passed to the set() function, the final set will only contain one of those elements.

In addition, you can also use curly braces {} to create collection objects, for example:

numbers = {1, 2, 3, 4, 5}


{1, 2, 3, 4, 5}

It is important to note that using curly braces {} to create an empty set will actually create an empty dictionary object, not an empty set. To create an empty set, you can use the set() function, for example:

empty_set = set()
