   • Create a Set in Python. 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.).
   • Create an Empty Set in Python. 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.
   • Duplicate Items in a Set. Let's see what will happen if we try to include duplicate items in a set. numbers = {2, 4, 6, 6, 2, 8} print(numbers) # {8, 2, 4, 6}
   • Add and Update Set Items in Python. 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.

   What is a Python set?

   • A Python set is a collection of distinct elements. The set has some things in common with Python lists and tuples, but there are important differences: More formally: sets are unordered collections of distinct objects. In this article, we’ll closely examine sets and how to use them.

   How do I create a set in Python?

   • To create a set from scratch and directly add some elements to it, you can use curly braces: Sets use the same curly braces as Python dictionaries, but they are easy to distinguish because a set always contains a sequence of elements separated by commas. In contrast, dictionaries contain key-value pairs that are specified with colons.

   What is set type in Python?

   • Summary: in this tutorial, you’ll learn about Python Set type and how to use it effectively. A Python set is an unordered list of immutable elements. It means: Elements in a set are unordered. Elements in a set are unique. A set doesn’t allow duplicate elements. Elements in a set cannot be changed.

   What are elements in a set in Python?

   • Elements in a set are unordered. Elements in a set are unique. A set doesn’t allow duplicate elements. Elements in a set cannot be changed. For example, they can be numbers, strings, and tuples, but cannot be lists or dictionaries. To define a set in Python, you use the curly brace {}.
