Actual behavior

When adding new line within brackets, the indentation does not conform to PEP8 format. E.g.

some_list = [item1,<press enter here>
<cursor gets to here>

Expected behavior

some_list = [item1,<press enter here>
             <cursor expected to be here>

I'm not sure if this is a python extension related issue or maybe VS code issue. I'm also using Vim, which has an extension specifically for this: https://github.com/Vimjas/vim-python-pep8-indent. It would be nice if this feature can be added to the extension. Thanks.
