python class: public, private, and protected members
in python, class members can have different levels of visibility and accessibility. understanding these levels of visibility—public, private, and protected—helps in designing clean and maintainable code. in this tutorial, we will explore how to define and use public, private, and protected members within python classes.
public members are accessible from outside the class. they can be accessed using the dot (.) operator directly.
private members are not accessible from outside the class. they are defined by prefixing the member name with double underscores (__).
however, python does not have true private members like some other languages. python uses name mangling to effectively make a member private, but it can still be accessed in a roundabout way.
protected members are accessible within the class itself and its subclasses. they are defined by prefixing the member name with a single underscore (_), although it's more of a convention rather than a strict rule.
understanding the concepts of public, private, and protected members in python classes is crucial for writing clean and maintainable code. public members provide easy accessibility, private members ensure encapsulation and data hiding, and protected members allow controlled access within the class hierarchy. proper usage of these member types enhances code readability and maintainability.
