Summary -- This PR implements the black preview style from https://github.com/psf/black/pull/4720. As of Python 3.14, you're allowed to omit the parentheses around groups of exceptions, as long as there's no `as` binding: **3.13** ```pycon Python 3.13.4 (main, Jun 4 2025, 17:37:06) [Clang 20.1.4 ] on linux Type "help", "copyright", "credits" or "license" for more information. >>> try: ... ... except (Exception, BaseException): ... ... Ellipsis >>> try: ... ... except Exception, BaseException: ... ... File "<python-input-1>", line 2 except Exception, BaseException: ... ^^^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: multiple exception types must be parenthesized ``` **3.14** ```pycon Python 3.14.0rc2 (main, Sep 2 2025, 14:20:56) [Clang 20.1.4 ] on linux Type "help", "copyright", "credits" or "license" for more information. >>> try: ... ... except Exception, BaseException: ... ... Ellipsis >>> try: ... ... except (Exception, BaseException): ... ... Ellipsis >>> try: ... ... except Exception, BaseException as e: ... ... File "<python-input-2>", line 2 except Exception, BaseException as e: ... ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: multiple exception types must be parenthesized when using 'as' ``` I think this ended up being pretty straightforward, at least once Micha showed me where to start :) Test Plan -- New tests At first I thought we were deviating from black in how we handle comments within the exception type tuple, but I think this applies to how we format all tuples, not specifically with the new preview style. |
