It's a way to write netlists in Python. As someone who uses both Python and does PC board design, this seems useless.

If you want to code something useful in that space, write an open source auto-router. The one for KiCAD no longer works and has IP problems. The author worked for a company that sold an auto-router, and they're unhappy about open source competition.

Or work on KiCAD bugs. KiCAD, which comes from CERN, is open source, but rather buggy. Most of the bugs are UI bugs, which requires good taste in UI to fix.
