#BASIC DATA STRUCTURES TUTORIAL CODE#

To keep things performant, strongly-typed languages build upon tried-and-tested data structures that offer the best possible methods for solving computational problems. On the other hand, data structures are the implementation of those ADTs. The Python equivalent would be the class methods over data types, such as round(float) or str.upper() or dict.keys(). ADTs offer groups of operations that you can perform over a data type.

In those strongly-typed languages, ADTs are an abstraction that saves us from writing computer code ourselves. In traditionally favored programming languages like Java and C++, the languages draw a strong distinction between Abstract Data Types (ADT) and Data Structures. How, if at all, do data structures differ from data types in Python? 1.1 How do Python data structures differ from data types?

Offer code examples for implementing it in the Python programming language.īefore we do that, we first need to clarify a murky boundary.

Showcase its importance and applications.

We have touched on some data structures before - you may remember the dictionary in Python, which is highly performant (O(1) time complexity at retrieving values stored in a dictionary when given a key).įor now, though, we will dive deeper into the classic and fundamental data structures:įor each data type, we will do three things:

They occupy the in-between world of highly performant machine code on one hand, and easy-to-comprehend abstracted functions on the other.ĭata structures describe how data should be organized so that it solves a computational problem while making its storage (space) complexity and time complexity as optimized as possible. Data structures sit at the intersection between computer science and data science.
