Python DSA

This lesson is part of Python · All levels

Summary

This lesson introduces the concept of data structures & algorithms (DSAs) within Python, which is how to store data in an organized manner with the algorithms to process it. You'll learn to pick the data structure that best suits your needs, from lists, stacks, queues, to graphs. Understanding DSA becomes an important foundation before you move on to database materials like MySQL and MongoDB.

Key points

Data structure is the way data is stored and organized, whereas algorithms are the step-by-step processes of that data.
Linear data structures such as lists, stacks, and queues are easily accessible in sequence, whereas trees and graphs are non-linear.
Complexity means that the work time grows in proportion to the amount of data.
Choosing the right data structure makes the program faster and more memory-efficient.
