How can I implement private attributes in Python?
In Python, you can implement private attributes by prefixing the attribute name with two underscores. For example, __my_private_var
.
What happens if I try to access a private attribute from outside the class?
If you try to access a private attribute from outside the class, you'll get an AttributeError. Python name-mangles the attribute to prevent access.
Can I still access it using the class name?
Yes, you can access it using the class name with the syntax ClassName._ClassName__my_private_var
.
Are there any best practices for using private attributes?
It's best to use private attributes for internal state management and provide public methods for accessing or modifying them.
