12 wrz 2024 · A Set in Python programming is an unordered collection data type that is iterable and has no duplicate elements. While sets are mutable, meaning you can add or remove elements after their creation, the individual elements within the set must be immutable and cannot be changed directly.
Defining a Set. Python’s built-in set type has the following characteristics: Sets are unordered. Set elements are unique. Duplicate elements are not allowed. A set itself may be modified, but the elements contained in the set must be of an immutable type. Let’s see what all that means, and how you can work with sets in Python.
4 wrz 2023 · In a nutshell, sets in Python are a mutable collection of unordered, unique immutable elements. Here’s what each of these attributes mean: Being mutable means that Python sets are changeable and do not have a fixed size: you can add and remove elements from a single set.
20 lis 2023 · Python Sets Are Mutable. As a mutable data structure, a Python set can dynamically change the elements it contains. This behavior is on par with most other data structures in Python, such as lists and dictionaries. In the example below, we start with an empty set and sequentially put new elements in it using the .add () method:

More formally: sets are unordered collections of distinct objects. In this article, we’ll closely examine sets and how to use them.
