Which TWO of the following are built-in Python decorators?

Which THREE of the following are valid ways to define abstract methods in Python?

You are utilizing abstract base classes (ABCs). How do you enforce that a subclass implements a specific method?

You need to ensure that a class can only be instantiated once throughout the application lifecycle. Which design pattern is most appropriate?

When writing a context manager using the @contextlib.contextmanager decorator, what should the function do to pass a value to the 'as' clause?

You need to dynamically add methods to a class at runtime. Which mechanism allows you to modify the class object before it is fully constructed?

When optimizing Python code, which tool should you use to identify hot spots in the execution path?

You are designing a class hierarchy where a subclass needs to ensure it calls the constructor of its parent in a multiple inheritance scenario. Which mechanism is the standard Pythonic approach to handle this dynamically?

You have a performance-critical application using heavy objects. You want to reduce memory footprint by preventing the creation of __dict__ for every instance. How should you proceed?

You are profiling your code and identify that a specific method is called millions of times. You decide to use a descriptor to optimize attribute access. What must the descriptor implement to intercept attribute assignment?

You need to compare two objects for equality based on a custom attribute. Which method should you override?

You are handling large datasets and want to improve memory efficiency. Which Python feature allows you to iterate over a large sequence without loading it entirely into memory?

Which magic method is used to define how an object is displayed for developers (for debugging)?

Which built-in function allows you to retrieve an attribute from an object by its string name?

In a multi-threaded application, you need to ensure that shared state is modified safely. Which tool is the most appropriate for this task?

You need to prevent an object's attribute from being modified after it is set. Which approach provides the most robust implementation?

When managing resources like file handles, what is the best practice to ensure they are always closed?

You have an object that behaves like a function. Which magic method must be implemented to make this possible?

Which keyword is used to raise an exception in Python?

You want to store an object in a set. What must the object implement?
