You might have been better off reading the text after the code example that came after the code you quoted.
The text read:
- Second example is much better. Finding files is the problem of temporary_files() and not of main()’s. This code is also testable, by unit testing of temporary_files().
- If you try to test the first example, you will mish mash finding temporary files with main algorithm.
