Aug 16, 2024 · In this article, we will discuss the Data Structures in the Python Programming Language and how they are related to some specific Python Data Types. We will discuss all the in-built data structures like list tuples, dictionaries, etc. as well as some advanced data structures like trees, graphs, etc.

Apr 7, 2025 · Python has three mutable data structures: lists, dictionaries, and sets. Immutable data structures, on the other hand, are those that we cannot modify after their creation. The only basic built-in immutable data structure in Python is a tuple.

Mar 11, 2025 · In Python, a list is a built-in dynamic sized array (automatically grows and shrinks). We can store all types of items (including another list) in a list.

Apr 25, 2014 · List objects are implemented as arrays. They are optimized for fast fixed-length operations and incur O (n) memory movement costs for pop (0) and insert (0, v) operations which change both the size and position of the underlying data representation.

To suit different uses, there are different data structures in Python. These can be mainly classified into two types: 1. Python Built-in data structures: These are the data structures that come along with Python and can be implemented same as primitive data types like integers, etc. These can be further classified into: a. Lists. b. Sets. d.

Mar 28, 2025 · In Python, different data structures let us access and manage data. Using the right data structure can make programs run faster and use less memory.
