一、请在草稿纸上手写一个单例模式的实现代码，拍照提交作业。单例模式
二、请用组合设计模式编写程序，打印输出图 1 的窗口，窗口组件的树结构如图 2 所示，打印输出示例参考图 3。﻿
                                                                                  
组合模式程序：
class ComponentBases(object):
    def __init__(self, name):
        self.name = name
    def add(self, obj):
        pass
    def remove(self, obj):
        pass
    def display(self, number):
        pass
class Node(ComponentBases):
    def __init__(self, name):
        self.name = name
        self.children = []
    def add(self, obj):
        self.children.append(obj)
    def remove(self, obj):
        self.children.remove(obj)
    def display(self, number=1):
        print(f"print {self.name}")
        n = number + 1
        for obj in self.children:
            obj.display(n)
if __name__ == '__main__':
    window_form = Node('window form(WINDOW窗口)')
    picture_logo = Node('Picture(LOGO图片)')
    window_form.add(picture_logo)
    button_log_in = Node('Button(登陆)')
    window_form.add(button_log_in)
    button_register = Node('Button(注册)')
    window_form.add(button_register)
    frame = Node('Frame(FRAME1)')
    window_form.add(frame)
    lable_username = Node('Lable(用户名)')
    frame.add(lable_username)
    textbox_username = Node('TextBox(文本框)')
    frame.add(textbox_username)
    lable_password = Node('Lable(密码)')
    frame.add(lable_password)
    textbox_password = Node('TextBox(密码框)')
    frame.add(textbox_password)
    checkbox = Node('CheckBox(复选框)')
    frame.add(checkbox)
    textbox_remember_username = Node('TextBox(记住用户名)')
    frame.add(textbox_remember_username)
    linklable = Node('LinkLable(忘记密码)')
    frame.add(linklable)
    window_form.display()
运行结果：
print window form(WINDOW窗口)
print Picture(LOGO图片)
print Button(登陆)
print Button(注册)
print Frame(FRAME1)
print Lable(用户名)
print TextBox(文本框)
print Lable(密码)
print TextBox(密码框)
print CheckBox(复选框)
print TextBox(记住用户名)
print LinkLable(忘记密码)
