本关任务:编写一个小程序绘制七段数码管,20200214, 其中灰色直线是画布的横轴和纵轴,作为绘图参照物,绘图时不需绘制。 编程要求 根据提示,在右侧编辑器补充完整函数,绘制如上图所示的当前日期的数码管。

import turtle
import datetime

def drawLine(draw):   # 绘制单段数码管
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    turtle.right(90)

def drawDigit(digit):   # 根据数字绘制七段数码管
    drawLine(True) if digit in [2,3,4,5,6,8,9] else drawLine(False)
    drawLine(True) if digit in [0,1,3,4,5,6,7,8,9] else drawLine(False)
    drawLine(True) if digit in [0,2,3,5,6,8,9] else drawLine(False)
    drawLine(True) if digit in [0,2,6,8] else drawLine(False)
    turtle.left(90)
    drawLine(True) if digit in [0,4,5,6,8,9] else drawLine(False)
    drawLine(True) if digit in [0,2,3,5,6,7,8,9] else drawLine(False)
    drawLine(True) if digit in [0,1,2,3,4,7,8,9] else drawLine(False)
    turtle.left(180)
    turtle.penup()
    turtle.fd(20)

def drawDate(date):   # 获取要输出的数字并绘制数码管
    for i in date:
        if i == '-':
            turtle.write('年', font=('Arial', 18, 'normal'))
            turtle.pencolor("green")
            turtle.fd(40)
        elif i == '=':
            turtle.write('月', font=('Arial', 18, 'normal'))
            turtle.pencolor("blue")
            turtle.fd(40)
        elif i == '+':
            turtle.write('日', font=('Arial', 18, 'normal'))
        else:
            drawDigit(eval(i))   # 通过 eval() 函数将数字变为整数

def main():
    turtle.setup(800, 350, 200, 200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    drawDate(datetime.datetime.now().strftime('%Y-%m=%d+'))
    turtle.hideturtle()
    turtle.done()
