PEP-0636 Structural Pattern Matching: Tutorial

Black formating

Python 3.10 & black, hmmm. Black won’t support structural pattern matching right away.

The entire file is parsed, including pieces between “#fmt:” comments. You will need an updated version of Black .

I think you can turn off formatting for certain lines ( instead of
the entire file) using::

    # fmt: off

    Code you want black
    To ignore...

    # fmt: on
