In this chapter, we learned about writing Python software that works well across multiple platforms. You learned how to avoid common platform pitfalls in Python code and how to write software that intelligently adapts to the needs of different operating systems. You also learned about published guidelines that help developers write software that meets platform users' expectations.
In the next chapter, we're going to learn about automated testing. You'll learn to write tests that ensure your code works correctly, both for regular Python code and specifically for Tkinter code, and to take advantage of the testing framework included in the Python standard library.
