This seems like a straightforward operation but I am stumped.
How do you set value of current Numbers cell using Py-Appscript?
Pretty tediously, but working:
>>> from appscript import *
>>> app('Numbers').documents.first.sheets.first.tables.first.selection_range.cells.first.value.set(to=42)
That's assuming a simple document. More generally, you can select items by name:
>>> app('Numbers').documents['MyDocument.numbers'].sheets['MySheet'].tables['MyTable'].selection_range.cells.first.value.set(to='abc')
