If a wooden bench is made of wood, what is a garden bench made of?

SD I had never noticed the usage of variable to mean attribute until a few

SD describing dictionary keys as dictionary variables?

If you google for 'instance variable python' you get quite a number of
hits, not only recent ones. Albeit two orders of magnitude fewer than
for 'attribute python'.

Sorry to pick on Diez, he's not the only one, just the latest example.
