This post shows you how to use arrays in Python and why this data structure is so useful. A foundational skill for data science, coding, and more!

Python uses zero-based array indexing. In most languages, Python and C included, the first element of an array is accessed with a zero—e.g., string [0] in Python for the first character in a string.

In this module the student will learn the very basics of algorithms through three examples: insertion sort (sort an array in ascending/descending order); binary search: search whether an element is ...
