Hi @andreamust

is there a way to print only the attributes without the node identifiers?

Not to my knowledge – of course, you can implement a function that does exactly that, if you want.

Another comment for @bluebell94: use appropriate attribute names for specifying values – e.g. I do not expect to have a name associated to the attribute weight, bur rather a number. If you want to specify the names as attributes, please look at the way @andreamust did.
