TL ; DR:
Python has no
public/privatekeywords. Privacy is signalled by naming convention:name— public, anyone can read/write._name— "internal", treat as private (the underscore is a hint to other programmers).__name— name-mangled to_ClassName__nameto avoid subclass collisions.
Nothing actually stops outside code from reading
obj._name. The convention is enforced socially, not by the runtime.
Full lesson:
In Java/C#/C++, the language stops you from reading a private field. In Python, the philosophy is "we're all consenting adults" — the language assumes you read the docs and respect the prefix.
The convention
class Dog:
def __init__(self, name):
self._name = name # "private by convention"
def get_name(self):
return self._name
Outside code could still write rex._name, but it shouldn't — the underscore signals "internal, may change without notice".
Your task
The Dog constructor stores the name as self._name. Add a get_name(self) method that returns it.
