Consider the following program: class Dinosaur : def __init__(self, name: str = “dinosaur”) -> None: self._name = name def display(self) -> None: print(self._name) class Triceratops(Dinosaur) : def __init__(self) -> None: super().__init__(“triceratops”) x = Triceratops() x.display() What is displayed when it executes?

You are creating a Motorcycle class which is supposed to inherit from the Vehicle class. Which of the following class declaration statements will accomplish this?

Consider the following class hierarchy: class Animal:    def speak(self) -> str:        return “???”     def shout(self) -> str:        return self.speak().upper() class Dog(Animal):    def speak(self) -> str:        return “woof” def main() -> None:    animals: list[Animal] = [ Dog() ]    print( animals[0].shout() ) main()

Consider the following code snippet: aVehicle = Auto() aVehicle.moveForward(200) If the Auto class inherits from the Vehicle class, and both classes have an implementation of the moveForward method with the same set of parameters, which statement is correct?

Consider the following hierarchy representing a Report (or memorandum) class Report:    def __init__(self, title: str) -> None:        self._title = title     def render(self) -> str:        raise NotImplementedError(“bad”) class BrokenReport(Report):    def __init__(self, title: str) -> None:        super().__init__(title)     def __repr__(self) -> str:        return f”BrokenReport(title={self._title}, output={self.render()})” def main() -> None:    items: list[Report] = [BrokenReport(“HW1”)]    print(items) main() What gets printed when the main is run?

Participation is based on completing weekly assignments, and absences will be counted if students fail to submit work for the week.  

This course is laid out in modules. In each module, you will find a list of the learning objectives for the module, activities to complete, and a list of assignments for the module.

First, the good news: Americans are definitely eating more healthful meals. We are consuming greater amounts of such high-fiber foods as whole-grain breads, fruits, and vegetables, which are believed to help prevent certain cancers and other diseases. At the same time, we are substituting relatively low-fat foods for higher-fat ones-for example, eating fish instead of red meat, drinking skim milk instead of whole. The bad news is that our snack foods are not nearly as healthful.)Between meals, we often revert to eating large amounts of fat. For instance, sales of ice cream and potato chips are going through the roof. Another drawback of the snack foods is that they have almost no fiber. As eating-behavior experts have concluded, we try super-hard to eat healthfully at mealtimes-but then undo some of the good work by “rewarding” ourselves with snacks that are bad for us.

In 1980 Mount St. Helens in Washington state erupted, killing nearly a hundred people and leveling thousands of acres of timber. By contrast, most Hawaiian volcanoes never erupt; instead, they simply emit flowing lava. Whether a volcano erupts or simply emits lava depends on the composition of its molten rock, which comes to the surface as lava. Volcanoes like Mount St. Helens have quick-cooling lava. As a result, the lava forms a dome that plugs the volcano’s hole. Eventually the pressure becomes so intense that a tremendous explosion blows off the lava dome and spews out a massive cloud of ash. Instead of hardening soon after it reaches air, the lava of most Hawaiian volcanoes flows down the cone’s sides until it encounters an obstacle or slowly cools into a solid. Because the lava never plugs the volcano, the volcano never erupts.
