@Meakk @snoyer do you know what we need to do to improve this ?

I believe it is generated through https://docs.python.org/3/library/pydoc.html so we'd need to study the documentation.

off the top of my head:

• having a doctring at the top of the file ("""triple quoted text""") should avoid it picking up the # This file is auto-generated by comment as description
• the internal stuff we don't want to show up can be prefixed with underscore to "make it private", ie. rename F3D_ABSOLUTE_DLLS to _F3D_ABSOLUTE_DLLS and so on
• not sure how to make it list the functions from the pybind lib tho
