Task 4: Docstrings

In the last workshop we dealt with a function called invert_image. You can find it in this package as well

your_package_name.processing.invert_image

Please write a docstring for that function. Here you can find more detailed instructions on Detailed Docstring.

Once you added a Docstring, please add another file that describes the process of inverting an image to the documentation. Then use the autofunction feature to include the Docstring into the documentation.

If you encounter an error like

WARNING: autodoc: failed to import function 'some.module'

make sure that you installed the package into your current enviroment.
