How to use a format map with remove_formats

[wrench100]

I'm trying to remove epub conversions from selected books. I've created a list of ID's using

ids=list(map(self.gui.library_view.model().id,rows ))

The docs for remove_formats says that I need to pass it "a mapping of book_id to a list of formats" but I have no idea how to do that.

Thanks!

Looking at the definition of "remove_formats", you need a dictionary where the keys are the ids of the books and the values are lists of the formats you want to remove.

Okay that makes sense. Thank you!
