WIP: Format Python with black
Not for merging.
Applied the black formatter to Gaudi, c.f. lhcb/LHCb#42., on top of !908 (closed). Done as:
black . 2> black.log
Log file available here.
I did not anticipate that, while black can in principle run over Python 2 files, it hesitates on files that cannot be parsed by the Python 3 AST parser. This behaviour can be overridden but I left these files unformatted for now.
