作业三：7段数码管绘制

算法说明：

运用turtle库实现画7段数码管

代码：

import turtle
import datetime

def drawgap():
    turtle.penup()
    turtle.fd(5)

def drawline(draw):
    drawgap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    drawgap()
    turtle.right(90)

def drawdigit(d):
    drawline(True) if d in [2, 3, 4, 5, 6, 8, 9] else drawline(False)
    drawline(True) if d in [0, 1, 3, 4, 5, 6, 7, 8, 9] else drawline(False)
    drawline(True) if d in [0, 2, 3, 5, 6, 8, 9] else drawline(False)
    drawline(True) if d in [0, 2, 6, 8] else drawline(False)
    turtle.left(90)
    drawline(True) if d in [0, 4, 5, 6, 8, 9] else drawline(False)
    drawline(True) if d in [0, 2, 3, 5, 6, 7, 8, 9] else drawline(False)
    drawline(True) if d in [0, 1, 2, 3, 4, 7, 8, 9] else drawline(False)
    turtle.left(180)
    turtle.penup()
    turtle.fd(20)

def drawdata(date):
    turtle.pencolor("red")
    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"))
            turtle.pencolor("black")
            turtle.fd(40)
        elif i == '*':
            turtle.write('小时', font=("Arial", 18, "normal"))
            turtle.fd(40)
        elif i == '/':
            turtle.write('分', font=("Arial", 18, "normal"))
        else:
            drawdigit(int(i))

def main():
    turtle.setup(1200, 350, 200, 200)
    turtle.speed(0)
    turtle.penup()
    turtle.fd(-500)
    turtle.pensize(5)
    current_time = datetime.datetime.now()
    drawdata(current_time.strftime('%Y-%m=%d+%H*%M/'))
    turtle.hideturtle()
    turtle.done()

main()

运行结果：
