I want to configure autopep8 as formatter in Visual Studio Code for my Python files.

In the documentation of the VSC Extension in the settings section, it is stated, that I can configure autopep8 with the keyword autopep8.args. the example is:

"autopep8.args" = ["--config", "<file>"]

But I don’t understand the documentation. Why is there an equal sign? In the VSC settings.json file, the configuration is in the format “key”: “value”. Therefore the supposed code doesn’t work like this.

What I have tried then is this in my settings.json file:

    "autopep8.args": [
        "--config", "~/DjangoKurs/techmax/.pep8"
    ]

and placed a .pep8 configuration file in the corresponding folder.
But it seems that this is the wrong way to read in my configuration settings for autopep8.

How to set this up correctly?
