Isn't clear still---too many unused variables. But you might need 
something like that:

for item in items:
     object_id = {} # new dict created
     object_id['id'] = 'anotherString'
     for i in range(10):
         p_settings = {} # new dict created
         for setting in myList[i]:
              p_settings[setting] = myString
     object_id['settings'] = p_settings
     object_perm_list.append(object_id)

BTW, dicts like {'id': smth, 'setting': smth} looks like objects to me.

And the last thing: it looks like you need to reread doc on references ;)
