Re-format all Python files using black [1] version 21.4b0.
This specific version (currently the latest) can be installed using:
$ pip3 install 'black == 21.4b0'
All you need to do to re-format files is run `black <file/directory>`,
and black will re-format any Python file it finds in there. It runs
quite fast, so the simplest is probably to do:
$ black gdb/
from the top-level.
