python-language-server config file location

Question

I'm trying to use flake8 as the default python linter using python-language-server on neovim v0.5.

python-lsp documentation says to set pylsp.configurationSources to ['flake8'], but doesn't specify which file to edit.

Where does the python-lsp-server config file reside?

According to flake8 documentation, the location of flake8 config varies based on systems, on Linux and Mac, it is ~/.config/flake8, and for Windows, it is $HOME\.flake8 ($HOME is like C:\\Users\sigmavirus24). The content should be in INI format:

[flake8]
max-line-length = 100
max-complexity = 30
ignore =
    # missing whitespace around arithmetic operator
    E226,
    # line break before/after binary operator
    W503,
    W504,
    # expected 1 blank line, found 0
    E301,E302,

To suppress a single warning, it is also handy to add # noqa: F841-like (change the code to the actual code you want to use) comment string to suppress it.
