That's what I take the word "when" to mean in the documentation:
https://docs.python.org/3/reference/datamodel.html#object.__del__

"Note: del x doesn’t directly call x.__del__() — the former decrements 
the reference count for x by one, and the latter is only called when x’s 
reference count reaches zero."
