excessive imports, import from notebooks?

@karnem @ahmedk

I would suggest to move this import (and similar in the other function) to the top of the module.

There is an import at the top of the module: import h5py, os, re

Yes, but import of glob is done in the functions, which is not a conventional way. I would suggest to move all imports to the top of the module.

That's something different. Maybe there was a reason for that - not to pollute the namespace.

Sounds convincing.

LGTM
