用Python编程绘制一个静态时钟，其边框为渐变色的圆。

可以使用Python的turtle库来绘制一个静态时钟，以下是一个简单的示例代码：

import turtle

# 设置画布大小和背景色
turtle.setup(500, 500)
turtle.bgcolor("black")

# 绘制时钟边框
turtle.speed(0)
turtle.pensize(3)
for i in range(120):
    turtle.color("white", "gray" + str(i % 10))
    turtle.begin_fill()
    turtle.circle(200, 3)
    turtle.left(3)
    turtle.end_fill()

# 绘制时钟刻度
turtle.penup()
turtle.goto(0, 180)
turtle.pendown()
turtle.color("white")
for i in range(12):
    turtle.forward(160)
    turtle.penup()
    turtle.forward(20)
    turtle.pendown()
    turtle.write(str(i+1), align="center", font=("Arial", 12, "normal"))
    turtle.penup()
    turtle.backward(180)
    turtle.left(30)

# 绘制时针、分针和秒针
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.pensize(5)
turtle.color("white")
turtle.right(90)
turtle.forward(100)
turtle.backward(100)
turtle.left(90)
turtle.pensize(3)
turtle.color("red")
turtle.forward(120)
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.pensize(2)
turtle.color("white")
turtle.right(90)
turtle.forward(150)
turtle.backward(150)
turtle.left(90)
turtle.pensize(1)
turtle.color("green")
turtle.forward(180)

# 隐藏画笔
turtle.hideturtle()

# 显示画布
turtle.done()

这段代码使用turtle库绘制了一个静态时钟，时钟边框为渐变色的圆，时针、分针和秒针分别为红色、白色和绿色。你可以在自己的Python环境中运行这段代码，看看效果如何。
