Check if feature attribute is empty in QGIS with pythonPython

I want my pythonPython script to do something when 2two feature attribute values are None at the same time. 

So I made this ifif statement: if feature["Name"] and feature["Zon"] is None:, but the code stops there and doesn't continue. Before the ifif statement I print both feature attribute values and get the following: (None, None). So the code should theoretically work, but it doesn't. What am I missing?
