Context:

• When a function has many parameters, it's more readable when on multiple lines, enforcing black to wrap lines adding a comma after the last parameter.
• See https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#how-black-wraps-lines

def func(a: int, b: int) -> int:
    return a + b 

def func(
    a: int,
    b: int,
) -> int:
    return a + b

python 3.12 new feature:

• https://docs.python.org/3/whatsnew/3.12.html#summary-release-highlights
• A generic function can now have type parameters used by the static type checker.
• See PEP 695, type parameter syntax and the type statement
• See https://peps.python.org/pep-0695/#summary-examples

def func[T](a: T, b: T) -> T:
    return a

Example in the current Black style:
Enforcing black to wrap lines gives the ugly:

def func[
    T
](a: T, b: T,) -> T:
    return a

Desired style:

def func[T](
    a: T,
    b: T,
) -> T:
    return a + b
