Access Modifiers in Python

Python uses naming conventions more than private keywords. normal_name is public. _name means “internal / subclass, please don’t touch” — convention only. __name inside a class triggers name mangling so outside access is harder. There is no true private like Java. Culture: we’re all adults, follow the underscore.

Viva — explain _, __, and that privacy is by convention. Don’t claim __ makes it encrypted. It only mangles the name.

Access Modifiers in Python — output — 1 2. pub and _hint readable. __hide is name-mangled — don’t touch from outside.

Exam tip

_ vs __ difference.

Example

# Access modifiers
class A:
    def __init__(self):
        self.pub = 1
        self._hint = 2
        self.__hide = 3

a = A()
print(a.pub, a._hint)

Access Modifiers in Python — output: 1 2. pub and _hint readable. __hide is name-mangled — don’t touch from outside.

Short notes

DefPublic: normal names
Rule_ protected convention
Remember__ name mangling
