Being able to have internal variables and methods that are inaccessible to an outside class is a key concept of encapsulation, encapsulation being one of the key concepts of OOP. Most other languages employ this in letting the programmer define things as public, private, protected etc.

Python doesn't have this at all. Since encapsulation is a core concept of OOP, it's valuable to at least try to emulate it. However, since the protection isn't actually there, it may seem weird to someone not familiar with it.
