（一）、设计实现电子算盘，并完成测试
【题目描述】
给小朋友设计一个电子算盘。要求绘制电子算盘界面，设计并实现打珠算过程（界面参考如下图示）。
界面右侧要求以图形绘制的方式绘制自画像，注意不能是图像文件显示的形式。
【源代码程序】
from tkinter import *
class Bead:
def __init__(self, canvas, x0, y0, x1, y1, fill):
self.canvas = canvas
self.id = canvas.create_oval(x0, y0, x1, y1, fill=fill)
self.canvas.tag_bind(self.id, "<Button-1>", self.move_up)
self.canvas.tag_bind(self.id, "<Button-3>", self.move_down)
def move_up(self, event):
if float(self.canvas.coords(self.id)[1]) - 20 >= 40:
self.canvas.move(self.id, 0, -20)
def move_down(self, event):
if float(self.canvas.coords(self.id)[1]) + 20 <= 350:
self.canvas.move(self.id, 0, 20)
class Abacus:
def __init__(self, window):
self.window = window
self.window.title("电子算盘")
self.window.geometry("800x500")
self.canvas = Canvas(window, width="800", height="500", bg="white")
self.canvas.pack()
self.create_abacus()
self.draw_self_portrait() # Draw self-portrait
def create_abacus(self):
# Draw frame
self.canvas.create_rectangle(25, 40, 450, 400, width=3)
# Draw beads
for i in range(5):
Bead(self.canvas, 40 + i*80, 60, 100 + i*80, 90, 'purple')
for j in range(4):
Bead(self.canvas, 40 + i*80, 160 + j*60, 100 + i*80, 190 + j*60, 'pink')
# Draw separators
for y in range(100, 400, 60):
self.canvas.create_line(25, y, 450, y, width=3)
def draw_self_portrait(self):
# Draw head
self.canvas.create_oval(600, 30, 700, 130, fill='lightblue')
# Draw facial features
self.canvas.create_line(630, 70, 670, 70, width=5) # Eyes
self.canvas.create_line(650, 90, 650, 110, width=5) # Nose
self.canvas.create_arc(630, 100, 670, 120, start=0, extent=180, width=5) # Mouth
# Draw body
self.canvas.create_rectangle(610, 150, 690, 250, fill='lightgreen')
if __name__ == "__main__":
window = Tk()
abacus = Abacus(window)
window.mainloop()
【运行测试】
（二）、以（一）中的电子算盘为基础，设计并实现珠算测试器，并完成测试。
【题目描述】
给小朋友设计一个珠算测试器，要求能够完成珠算加减法的测试。具体的要求功能如下：
(1) 用户启动测试，输入用户名后系统随机生成特定数目的加减法测试题；
(2) 要求测试使用表盘式或数字时秒表进行界面计时显示（参考如上图示）；
(3) 对于每道测试题目，要求用户使用电子算盘完成珠算过程，当按下确认键时，将珠算结果与正确答案比对，并在界面上显示总题数、已答题数和已做对题数；
(4) 当测试完成，界面显示本次测试情况（包括用户名、测试题目及答题明细、对错情况、测试用时和测试成绩）
