作业4-1. 定义二维空间下的几何图形类circle（圆）、ellipse（椭圆）、rectangle（矩形）和square（正方形）。每个类中包含初始化方法和paint方法，其中paint方法实现图形信息的输出（如“半径是1、圆心在(0, 0)的圆”）。其中circle类继承ellipse类，square类继承rectangle类。
class ellipse(object):
def __init__(self):
print('ellipse')
def paint(self):
print('半径是1﹑圆心在(0,0)的圆')
class rectangle(object):
def __init__(self):
print('rectangle')
def paint(self):
print('边长是2正方形')
class circle(ellipse):
def __init__(self):
print('circle')
super(circle, self).__init__()
super(circle, self).paint()
class square(rectangle):
def __init__(self):
print('square')
super(square, self).__init__()
super(square, self).paint()
ellipse().paint()
rectangle().paint()
circle()
square()作业4-2. 定义一个类Person，其中包含name(姓名)、sex(性别)、age(年龄)、address(住址)、email(电子邮箱)、phone(电话号码)等信息，然后在此基础上定义Student(学生)、Staff(员工)，并在Staff基础上定义Teacher(教师)。要求：Student有一个dict属性记录其每门课程的学分，Staff至少有一个salary属性表示其薪水，Teacher有一个list对象存储其能教授的所有课程。在这些类的基础上编写一个简单的学校人员管理程序，包含输入、查找、修改、删除、显示等操作。
