None / nobody разница?

Nobody - никто (Nobody knows where he is.). None - никто (We expected visitors,but none came.),ничто (We expected letters,but none came),ни один из (None of us have come to the party).После nobody не употребляется предлог "of".

Nobody was there.
None of them was here.

(nobody - никто, none - ни один из)

No new ничто, nobody-никто
