I think python only has 3 unary operations, + - and ~ and only + and -
can also be binary operations.

unary + has less uses, since it normally just passes its argument, if
valid, unchanged, but can be used to validate that its argument has the
right type. I am not sure if a type could define its own unary+ to do
something special, but I thought it could.

Yes, it can via the __pos__ dunder.
