可以在 drawDate(date) 函数中，将字符串格式的时间转换成年月日时分秒格式，并依次调用 drawDigit(d) 函数绘制数字时钟。然后使用 Python 的 time 模块来实现时间的实时更新。具体实现如下所示：

import turtle
import datetime
import time

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 drawDate(date):
    turtle.pencolor("red")
    for i in date:
        if i == '-':
            turtle.write('年', font=('Arial', 18, 'normal'))
            turtle.pencolor('green')
            turtle.fd(40)
            turtle.write('月', font=('Arial', 18, 'normal'))
            turtle.pencolor('blue')
            turtle.fd(40)
            turtle.write('日', font=('Arial', 18, 'normal'))
            turtle.pencolor('purple')
            turtle.fd(40)
            turtle.write('时', font=('Arial', 18, 'normal'))
            turtle.pencolor('orange')
            turtle.fd(40)
            turtle.write('分', font=('Arial', 18, 'normal'))
            turtle.pencolor('black')
            turtle.fd(40)
            turtle.write('秒', font=('Arial', 18, 'normal'))
            turtle.pencolor('red')
            turtle.fd(40)
        elif i == '+':
            pass
        else:
            drawDigit(eval(i))

def main():
    turtle.setup(800, 350, 200, 200)
    turtle.penup()
    turtle.fd(-350)
    turtle.pensize(5)

    while True:
        drawDate(datetime.datetime.now().strftime('%Y-%m-%d+%H%M%S'))
        turtle.clear()
        time.sleep(1)

if __name__ == '__main__':
    main()

这样就可以实现数字时钟的实时更新了。
