I finally caught on to the "Run Pythonista Script" widget when called from another app. FileBrowser has been a big help with exporting from Pythonista. I can select a group of .py files, using the Save to Files widget, and my past use of FileManager as the receiver makes it so that it immediately brings up the DropBox folder I used previously.
