python class private methods

in python, class methods and attributes can be categorized into three levels of visibility:
in this tutorial, we'll focus on private methods, how to define them, and when to use them.
to define a private method in a python class, use a double underscore prefix before the method name. for example:
here, __private_method is a private method, and __private_var is a private attribute.
accessing private methods is possible, but it's not recommended. python uses name mangling to make it more challenging to access these methods from outside the class. however, it's still possible. here's how you can access a private method:
note that this is not considered good practice, and you should avoid accessing private methods directly from outside the class.
private methods are primarily used for internal class logic and should not be part of the class's public api. they help in encapsulating and organizing the class's functionality. here are some common use cases for private methods:
helper functions: private methods can be used to define helper functions that are only relevant within the class. these functions can assist in performing various tasks without cluttering the public interface.
avoiding name clashes: private methods help avoid naming conflicts with methods or attributes in derived classes. name mangling ensures that the private method's name includes the class name as a prefix.
enhancing readability: private methods can enhance the readability of a class by breaking down complex logic into smaller, more manageable pieces.
enforcing access control: while not foolproof, private methods can serve as a form of access control, discouraging external code from using them.
private methods in python classes, indicated by a double underscore prefix, are meant for internal class logic and are not part of the class's public api. they help encapsulate functionality, enhance code organization, and reduce naming conflicts. while it's possible to access them from outside the class, it ...
