Welcome! In programming, just like playing a favorite song on repeat, loops execute code repeatedly. Here, we'll explore the "For Loop" in Python, an iteration construct over sequences such as lists or strings.

Imagine a train journey: the train represents our loop, stopping at each station. Each station represents an item on its route, which is the iterable.

Like replaying a song or game level, a loop continually executes a block of code until a defined condition is met. It's akin to saying, "Keep the popcorn machine running as long as the popcorn keeps popping!"

A Python For Loop looks like this:

In this construct, for and in are keywords. The variable holds the current item in each iteration, while iterable_object can be a list, string, or any object that provides an item sequentially.

Let's print all elements of a list:

This code will print every planet from the list (, , , ...), each on a separate line.
