How to Create a Well-Formatted XML File Using Python

Creating an XML file might seem straightforward, but if you’ve tried it out on your own, you may have ended up with a string of text that’s hard to read and not well-organized. In this guide, we'll tackle this problem: how to create a properly formatted XML file using Python. So, if your output isn't looking quite right—aligning in a single line instead of a structured format—don’t worry! We will guide you through the process step by step.

The Problem: Unformatted XML Output

You might have attempted to create an XML file using Python's ElementTree, only to find yourself frustrated with the resulting single-line output. For example, your initial code may have generated something like this:
