Not trying to be disparaging, but how much experience do you have working with Python and the libraries that are built with it? I routinely hit the source to see where things are going while working through stack traces or extending built-ins, and while it's not always crystal clear, I've rarely gotten the impression things were done in such a way as to be entirely unreadable or unforgivably abstracted.

I have lots of experience with python (>5 years, and +5 years of web-dev before that) and I have no problem reading some of challenging source code out there of course. I'm rather referring to quality of code itself from the perspective of Robert Martin's "Clean Code". I can't remember concrete bits of course, but it sure happened in past.
