How can a class method update a class-level attribute?

By using the self parameter to assign a new value.

By using the cls parameter to assign a new value.

In a class method, what does the cls parameter refer to?

The class on which the method was called.

The instance on which the method was called.

The module in which the class is defined.

A `ReportGenerator` class has a static method `format_header(title)` that returns a formatted header string, and a class method `generate()` that creates a report. The team wants `generate()` to use `format_header` to produce the header. However, they also want subclasses to be able to override `format_header` to customize the header format. Which approach allows `generate()` to call the overridden `format_header` in subclasses?

In `generate()`, call `ReportGenerator.format_header(title)`

In `generate()`, call `self.format_header(title)`

In `generate()`, call `cls.format_header(title)`

In `generate()`, call `format_header(title)` directly

When would you choose a static method over a class method?

When you need to access or modify class-level attributes.

When the method does not need access to the class or instance data.

When you want to create an alternative constructor for the class.

When you want the method to be inherited by subclasses.
