Regarding Step 3, I’m not clear why using get_link_node() is necessary

Referring specifically to the (apparently correct) code below:

dots_data = yacko.get_link_node().get_value()

Why not just write 'dots_data = yacko.link_node.get_value()? We’ve already set the link node as an attribute of the class in the set_link_node() method.

Edit: In fact, I’m not sure what the point of the get_link_node() or set_link_node() methods are at all, when we can just ‘get’ and ‘set’ using regular dot notation with class attributes.

My best guess is that they want to expose all behaviour through methods.
I don’t agree, in my eyes it’s dead code that makes it harder to see what’s actually being done.
