ConfigObj/ConfigParser vs. using YAML for Python settings file?

Using ConfigObj is at least very straightforward and ini files in general are much simpler (and more widely used) than YAML. For more complex cases, including validation, default values and types, ConfigObj provides a way to do this through configspec validation.

ConfigParser has a really bad API, ConfigObj is supposed to be good but I have never used it, for ini files I usually implement my own parser.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
