python电子时钟表盘

以下是Python电子时钟表盘的代码实现：

import turtle
import time

# 绘制表盘刻度
def drawLine(length, angle):
    turtle.penup()
    turtle.fd(length)
    turtle.pendown()
    turtle.fd(length/10)
    turtle.penup()
    turtle.backward(length*1.1)

    turtle.right(angle)

# 绘制表盘数字
def drawNum(num):
    turtle.penup()
    turtle.fd(200)
    turtle.right(90)
    drawLine(40, 0)
    turtle.write(num, font=('Arial', 18, 'normal'))
    turtle.left(90)
    turtle.backward(200)

# 绘制表盘
def drawClock(radius):
    turtle.pensize(7)
    for i in range(60):
        if i % 5 == 0:
            drawNum(i//5)
        else:
            drawLine(20, 0)
        turtle.right(6)
    turtle.penup()
    turtle.goto(0, -radius)
    turtle.pendown()
    turtle.circle(radius)

# 绘制指针
def drawPointer(length, width):
    turtle.pensize(width)
    turtle.fd(length)
    turtle.backward(length)

# 获取当前时间并更新指针位置
def getRealtime():
    turtle.penup()
    turtle.goto(0, 0)
    turtle.pendown()
    turtle.clear()
    turtle.pencolor('black')
    turtle.write(time.strftime('%H:%M:%S'), font=('Arial', 18, 'normal'))
    second = time.localtime().tm_sec
    minute = time.localtime().tm_min
    hour = time.localtime().tm_hour
    turtle.pensize(5)
    turtle.pencolor('red')
    turtle.seth(90)
    turtle.right(hour*30+minute*0.5)
    drawPointer(60, 5)
    turtle.seth(90)
    turtle.right(minute*6)
    drawPointer(100, 3)
    turtle.seth(90)
    turtle.right(second*6)
    drawPointer(120, 1)
    turtle.penup()
    turtle.home()

# 初始化
def init():
    turtle.setup(800, 600)
    turtle.pensize(7)
    turtle.speed(0)
    turtle.hideturtle()

# 主函数
def main():
    init()
    while True:
        getRealtime()
        time.sleep(1)

# 运行主函数
if __name__ == '__main__':
    main()
