How do I use private attributes in Python?

How do I use private attributes in Python?

In Python, you can define private attributes by prefixing the attribute name with two underscores, like this: __attribute.

Can you give me an example of a class with private attributes?

Sure! Here's a simple example:

class MyClass:
    def __init__(self):
        self.__private_attr = 42

    def get_private_attr(self):
        return self.__private_attr

In this example, __private_attr is a private attribute.

How can I access a private attribute from outside the class?

You can access it using a method within the class, like get_private_attr(), or by using name mangling, but it's not recommended.

What is name mangling?

Name mangling is a mechanism in Python that changes the name of a private attribute to include the class name, making it harder to access from outside.
