How to Do a Binary Search in Python

By · Published by Everything Blog

In short

The instructional material targets software developers already comfortable with classes, lambdas, recursion, and core language structures using Python 3.7 or newer. Developers analyze performance limitations and algorithmic variations using realistic data rather than artificial toy arrays. The testing process relies on an automated script to safely decompress and generate sorted names from a 600-megabyte Internet Movie Database archive without crashing text editors.

Binary search is a classic algorithm in computer science. It often comes up in programming contests and technical interviews. Implementing binary search turns out to be a challenging task, even when you understand the concept. Unless you’re curious or have a specific assignment, you should always leverage existing libraries to do a binary search in Python or any other language.

In this tutorial, you’ll learn how to:

- Use the

bisect

module to do a binary search in Python - Implement a binary search in Python both recursively and iteratively

- Recognize and fix defects in a binary search Python implementation

- Analyze the time-space complexity of the binary search algorithm

- Search even faster than binary search

This tutorial assumes you’re a student or an intermediate programmer with an interest in algorithms and data structures. At the very least, you should be familiar with Python’s built-in data types, such as lists and tuples. In addition, some familiarity with recursion, classes, data classes, and lambdas will help you better understand the concepts you’ll see in this tutorial.
