2 设计一个Course课程类该类中包括number编号、name名称、teacher任课教师、location上课地点共4个属性其中location是私有属性；还包括__init__、show_info显示课程信息共两个方法。设计完成后创建Course类的对象显示课程的信息。

class Course: def init(self, number, name, teacher, location): self.number = number self.name = name self.teacher = teacher self.__location = location

def show_info(self):
    print("课程编号：", self.number)
    print("课程名称：", self.name)
    print("任课教师：", self.teacher)
    print("上课地点：", self.__location)

course = Course("001", "Python编程", "张老师", "A201") course.show_info()
