设计一个课程类，该类有编号，名称，任课教师，上课地点4个属性，其中上课地点为私有属性，还包含构造函数和展示课程信息的方法，创建对象显示课程信息python

以下是一个可能的实现，其中上课地点为私有属性，使用了Python的property装饰器来实现访问和修改私有属性的方法。

class Course:
    def __init__(self, course_id, name, teacher, location):
        self.course_id = course_id
        self.name = name
        self.teacher = teacher
        self._location = location

    @property
    def location(self):
        return self._location

    @location.setter
    def location(self, new_location):
        self._location = new_location

    def show_info(self):
        print("Course ID:", self.course_id)
        print("Name:", self.name)
        print("Teacher:", self.teacher)
        print("Location:", self.location)

# 创建课程对象并显示信息
course1 = Course(1, "Math", "John Doe", "Room A101")
course1.show_info()

# 修改地点
course1.location = "Room B202"
course1.show_info()

输出结果：

Course ID: 1
Name: Math
Teacher: John Doe
Location: Room A101
Course ID: 1
Name: Math
Teacher: John Doe
Location: Room B202
