python中turtle绘制七段数码管

效果如下，思路是先绘制一条线，在绘制七条线，传入数字，如果数字绘制需要七段中某一位置有笔画，就绘制，无则不绘。

# coding=utf-8
import turtle, time


def drawGap():  # 绘制数码管间隔
    turtle.penup()
    turtle.fd(5)


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

# 绘制顺序是一定的，只要有数字就绘制，无就不绘制
def drawDigit(d):  # 根据数字绘制七段数码管
    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 drawDate(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"))
        else:
            drawDigit(eval(i))


def main():
    turtle.setup(800, 350, 200, 200)
    turtle.penup()
    turtle.fd(-350)
    turtle.pensize(5)
    #    drawDate(2018-10=10+)
    drawDate(time.strftime(%Y-%m=%d+, time.gmtime()))
    turtle.hideturtle()
    turtle.done()


main()
