Why do we used get() and set() methods instead of just getting data through node.name or node.size setting it through node.name = or node.size = ? . Going through this lesson I can substitute node.name for any node.get_name() and it doesn’t change the outcome (which makes sense since the method just returns node.name anyway). Feels like an extra step and I can’t figure out why we need it.


the extra step can be useful, for example if you have an array and you always want to return a string representation, then you can define getter to use each time, rather then using join everywhere.

these kind of abstractions become useful once your program becomes larger
