Can I have helper functions in a separate .py file?

Inside a package, I have defined functions on a type. Those functions use many helper functions that are currently in the same file. Is it possible to move those helper functions to another file? If so, I was wondering what is the correct way of importing them?

You can move them in into a separate type, and label that type as ‘private’ and the functions under that type as ‘private inline’, indicating that those function should only be used internally.
