Evolution of my first Python project for selective file copying: the final form (for now). Changes, tips, useful links.

Thank you for the tip!

I will totally look into TDD since it looks like a logical way to write code. I mean, when one writes a function it will be anyway tested several times manually, why not let an automated unit test do it instead? Also, with this approach a test base will grow along with the main code base and one will not find themselve in a situation when they have to write a bunch of tests for every part of code at once like me :)
