Mar 18, 2024 · Learn how to use set () function in Python to create or convert iterables to sets with distinct elements. See examples of set () with list, tuple, range and dictionary.
Definition and Usage. The set() function creates a set object. The items in a set list are unordered, so it will appear in random order. Read more about sets in the chapter Python Sets.

In Python, we create sets by placing all the elements inside curly braces {}, separated by commas. A set can have any number of items and they may be of different types (integer, float, tuple, string, etc.). But a set cannot have mutable elements like lists, sets or dictionariesas its elements. Let's see an example, Output In the above example, we ...
Creating an empty set is a bit tricky. Empty curly braces {}will make an empty dictionary in Python. To make a set without any elements, we use the set()function without any argument. For example, Output Here, 1. empty_set - an empty set created using set() 2. empty_dictionary - an empty dictionary created using {} Finally, we have used the type() ...
Let's see what will happen if we try to include duplicate items in a set. Here, we can see there are no duplicate items in the set as a set cannot contain duplicates.
Sets are mutable. However, since they are unordered, indexing has no meaning. We cannot access or change an element of a set using indexing or slicing. The set data type does not support it.
We use the discard()method to remove the specified element from a set. For example, Output Here, we have used the discard() method to remove 'Java' from the languagesset.
Here are some of the popular built-in functions that allow us to perform different operations on a set.
We can use the len()method to find the number of elements present in a Set. For example, Output Here, we have used the len()method to find the number of elements present in a Set.
Python Set provides different built-in methods to perform mathematical set operations like union, intersection, subtraction, and symmetric difference.
The intersection of two sets A and B include the common elements between set A and B. In Python, we use the & operator or the intersection()method to perform the set intersection operation. For example, Output Note: A&B and intersection() is equivalent to A ⋂ Bset operation.
The difference between two sets A and B include elements of set A that are not present on set B. We use the - operator or the difference()method to perform the difference between two sets. For example, Output Note: A - B and A.difference(B) is equivalent to A - Bset operation.
Nov 12, 2021 · Python provides various functions to work with Set. In this article, we will see a list of all the functions provided by Python to deal with Sets. Adding and Removing elements. We can add and remove elements form the set with the help of the below functions –. add (): Adds a given element to a set. clear (): Removes all elements from the set.
