This may be a good time to install black.

python -m pip install black

Here is a copy of the code.py file;

list_of_numbers = [
    1,
    2,
    3
]

large_dictionary = {1:2, 3:4, 5:6, 7:8, 9:10, 11:12, 13:14, 15:16, 17:18, 19:20, 21:22, 23:24}

This is the contents of the file before we apply black;

list_of_numbers = [
    1,
    2,
    3
]

large_dictionary = {1:2, 3:4, 5:6, 7:8, 9:10, 11:12, 13:14, 15:16, 17:18, 19:20, 21:22, 23:24}

This is the contents after black;

list_of_numbers = [1, 2, 3, 4, 5, 6, 7, 8]

large_dictionary = {
    1: 2,
    3: 4,
    5: 6,
    7: 8,
    9: 10,
    11: 12,
    13: 14,
    15: 16,
    17: 18,
    19: 20,
    21: 22,
    23: 24,
}

All code will be formatted, not mere data containers. So if we start with this;

def open_up_this_here_file(filepath: os.PathLike, read_method: str = 'w', verbose: bool = True, debug: bool = False):
    """Does a whole bunch of things this one function does right here."""
    with open(filepath, read_method) as f:
        print(f.read())

We will end up with;

def open_up_this_here_file(
    filepath: os.PathLike,
    read_method: str = "w",
    verbose: bool = True,
    debug: bool = False,
):
    """Does a whole bunch of things this one function does right here."""
    with open(filepath, read_method) as f:
        print(f.read())

It deserves to be said; black is opinionated.
