Others have tried to explain and pointed out you can del and then use the

But consider the odd concept of writing your own trivial function.

Or do you want to be able to call it as in dict.remaining(key) by
subclassing your own variant of dict and adding a similar method?

No, 'del' does indeed do what I wanted, although I have now decided I

exists, so that I don't have to reinvent it.
