poetry format is broken anyway with the same syntax error. This project shouldn't be shipping /usr/bin/format regardless (even if it worked).

Story:

$ format
  File "/usr/bin/format", line 8
    sys.exit(main.())
                  ^
SyntaxError: invalid syntax
$ # Huh? That's odd

$ cat /usr/bin/format
#!/usr/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from black import main
if __name__ == "__main__":
    sys.argv[0] = re.sub(r"(-script\.pyw|\.exe)?$", "", sys.argv[0])
    sys.exit(main.())

$ pacman -Qo /usr/bin/format
/usr/bin/format is owned by pacman-mirrors 4.27-1

$ # Great
