Explore object-oriented Python programming level 2 through activity 3, focusing on object creation, initialization, attributes, and methods with arguments.

Build a vendor info class in Python with attributes name, GST, place, and contact; implement init, display, and update methods, create three objects, and render updated details.

Analyze how class and object relationships influence attribute access and method calls in Python. Identify common type and attribute errors and practice object based initialization and attribute use.

Explore Python private attributes and double underscores, showing how accessibility differs inside and outside a class and how encapsulation can raise an attribute error.

Explore Python magic methods, or dunder methods, used to customize class behavior with initialization, length, string conversion, deletion, and callable instances.

Explore class vs. instance behavior: class variables, class methods, and instance methods; see how blueprint changes affect all objects and predict outputs, with attribute errors when data is missing.

Explore the property function and property decorator in python, learning how to use getters, setters, and deleters with four optional parameters to define and manage a property attribute.

Explore the property decorator to define getter and setter for a file system type and file system mode point, updating values dynamically without recreating objects.

Explore iterator concepts by building a while loop that consumes a list or iterable with next(), printing elements until StopIteration triggers and is handled to terminate safely.

Explore generator functions and generator expressions, reading large data efficiently with memory-friendly line-by-line processing, using yield and generator objects for recursive file and directory traversal.
