 - "dunder" -> "double under", referring to the names of these methods being prefixed with two underscores, e.g. `__init__`. There is no formal privacy in Python, but conventionally a single underscore indicates a private method, or one that the programmer should assume may change at any time; methods without an underscore are considered part of an object's public API. Double underscores are even more special - they are used by Python's builtin functions like `len()`, for example, to allow objects to implement various interfaces and functionality. They can also be used for operator overloading. If you have a custom class that you would like to be able to compare to other instances of the same class, implementing `__lt__`, `__gt__`, `__eq__` etc. allow programmers to use the `>`, `<`, `=` operators. Dunder methods allow programmers to build useful objects with simple interfaces, i.e. you can add two instances together using `+` instead of writing something like `instance1.add(instance2)`.
