The current indentation behavior for function parameters is: 4-space indentation at function definitions, like this:

def my_function(
    my_function_arg_1,
    my_function_arg_2,
    my_function_arg_3,
    my_function_arg_4,
):
    pass

This leads to reduced readability, because the function name and the argument names become harder to distinguish.

Adding one more level of indentation greatly improves readability:

def my_function(
        my_function_arg_1,
        my_function_arg_2,
        my_function_arg_3,
        my_function_arg_4,
):
    pass

PEP8 also has the same suggestion: https://peps.python.org/pep-0008/#indentation
