You have a response there, so I'm not sure why you're trying to
duplicate it here.

A portion of your question there:

That's not the whole error, that's just the last line of it.  Still the
immediate answer is clear:

after the statement
    import repository

one new symbol is available to your code, the symbol   'repository'

if you want to use something defined in that imported module, then use

obj = repository.Repository()



Or you could do one of these two:

import repository
Repository = repository.Repository   #defines new name for the class
Materials = repository.Materials       #ditto

or

from repository import Repository, Materials


In either of those latter cases, you could now create the object by

obj = Repository()

As for the Eclipse problem, you'll have to study the other answer;  I've
never found it worthwhile to install Eclipse for Python.
