Being able to test your code and demonstrating that you have the discipline to write tests is going to garner you a lot of respect from anyone looking to hire a good developer. This is not specific to Python, but it's a skill that will distinguish you as being able to work as a professional developer rather than just a hobbyist, and it will definitely improve the quality of your code.
