python时钟罗盘酷炫代码

以下是Python时钟罗盘的酷炫代码：

import turtle
import time

# 绘制刻度线和数字
def draw_line(m):
    turtle.pensize(3)  # 设置笔的大小
    for i in range(m):
        turtle.penup()
        turtle.goto(0, -240)
        turtle.pendown()
        turtle.forward(20)
        turtle.penup()
        turtle.goto(0, -260)
        turtle.write(i, align="center", font=("Arial", 12, "normal"))
        turtle.right(360 // m)

# 绘制指针
def draw_pointer(name, length):
    turtle.penup()
    turtle.goto(0, 0)
    turtle.color("red")
    turtle.setheading(0 - name * (360 // 12))
    turtle.pensize(5)
    turtle.pendown()
    turtle.forward(length)

# 绘制时钟罗盘
def draw_compass():
    turtle.setworldcoordinates(-300, -300, 300, 300)
    turtle.penup()
    turtle.speed(0)
    turtle.goto(0, -200)
    turtle.pendown()
    turtle.circle(200)
    turtle.penup()
    turtle.goto(0, -180)
    turtle.pendown()
    turtle.circle(180)
    turtle.penup()
    turtle.goto(0, -160)
    turtle.pendown()
    turtle.circle(160)

    draw_line(60)
    turtle.color("orange")
    draw_pointer(time.localtime().tm_sec, 120)

    turtle.color("blue")
    draw_pointer(time.localtime().tm_min, 100)

    turtle.color("green")
    draw_pointer(time.localtime().tm_hour % 12, 70)

    turtle.hideturtle()

# 主函数
if __name__ == '__main__':
    draw_compass()

    # 持续更新
    while True:
        turtle.color("orange")
        draw_pointer(time.localtime().tm_sec, 120)

        turtle.color("blue")
        draw_pointer(time.localtime().tm_min, 100)
        
        turtle.color("green")
        draw_pointer(time.localtime().tm_hour % 12, 70)

        time.sleep(1)

        turtle.undo()
        turtle.undo()
        turtle.undo()

这个代码使用了Turtle Graphics库来创建一个时钟罗盘。其中，利用time库来获取当前时间，以此来绘制三个指针。同时，我们使用循环来持续更新指针的位置，从而实现不断更新显示的效果。
