Looping through an array is one of the most elementary algorithms in programming. Often, it’s one of the first things a new developer does after “Hello, world!” The very principle of starting indices at zero was probably the first paradigm shift you encountered while learning to code. Yet, this is Python; loops and containers here operate on a whole different level.
