Introduction

A previous tutorial (about if statements and while loops) in this series explored the essence of decision-making with the if statement and ventured into the realm of repetition (or iteration) with the while loop statement. We compared how if and while loops let your code mimic human-like decision making processes on a shopping trip.

These constructs, you might also consider akin to the dials and switches on a machine, empower programmers to carve out dynamic pathways in their algorithms. However, as we push the boundaries of complexity especially for data science, another tutorial remains ahead: the for loop.

Abstract

Python, a prominent language in data science, offers an elegant and flexible construct for iteration: the for loop. This tutorial carefully explains its intricacies, the basic structure, and how it…
