### 设计 `Course` 类 以下是基于 Python 的 `Course` 类的设计实现，其中包含了指定的属性（编号、名称、教师、位置）以及初始化方法 (`__init__`) 和展示信息的方法 (`show_info`)。 此类遵循了良好的文档编写习惯[^1]，并提供了清晰的类说明和属性描述： ```python class Course(object): """ Represents a course with associated details. This class stores information about a specific course, including its number, name, teacher, and location. It also provides functionality to display this information in a formatted manner. Attributes: number (str): The unique identifier for the course. name (str): The full title of the course. teacher (str): The instructor's name responsible for teaching the course. location (str): The physical or virtual classroom where the course takes place. """ def __init__(self, number="", name="", teacher="", location=""): """ Initializes a new instance of the Course class. Args: number (str): Unique identifier for the course. name (str): Full title of the course. teacher (str): Instructor's name who teaches the course. location (str): Physical or virtual classroom where the course is held. """ self.number = number self.name = name self.teacher = teacher self.location = location def show_info(self): """ Displays detailed information about the course in a readable format. """ info = ( f"Course Number: {self.number}\n" f"Course Name: {self.name}\n" f"Instructor: {self.teacher}\n" f"Location: {self.location}" ) print(info) ``` #### 创建对象并调用方法 下面是一个简单的例子，演示如何实例化 `Course` 对象并调用其 `show_info()` 方法来显示课程详情： ```python # Create an object of the Course class course_example = Course( number="CS101", name="Introduction to Computer Science", teacher="Dr. Jane Smith", location="Room 205" ) # Display course information using the method course_example.show_info() ``` 运行上述代码会输出如下内容： ``` Course Number: CS101 Course Name: Introduction to Computer Science Instructor: Dr. Jane Smith Location: Room 205 ``` 此设计严格遵守了关于类定义中的文档字符串标准[^1]，并且通过提供详细的属性和方法解释增强了可读性和维护性。
