Typically, Python code strives to adhere to the Uniform Access Principle. Specifically, the accepted approach is: Expose your instance variables directly, allowing, for instance, foo.x = 0, not foo.set_x(0) If you need to wrap the accesses inside methods, for whatever reason, use @property, which preserves the access semantics. That is, foo.x = 0 now invokes … Read more
You could return an Integer instead of an int, returning null on parse failure. It’s a shame Java doesn’t provide a way of doing this without there being an exception thrown internally though – you can hide the exception (by catching it and returning null), but it could still be a performance issue if you’re parsing hundreds of thousands of … Read more

What is the precise difference between encapsulation and abstraction?
The name scrambling is used to ensure that subclasses don’t accidentally override the private methods and attributes of their superclasses. It’s not designed to prevent deliberate access from outside. For example: Of course, it breaks down if two different classes have the same name.
