编写个罗盘时钟代码 实现可以在电脑桌面直接展示

以下是使用Python和Tkinter库编写的罗盘时钟代码，可以在电脑桌面直接展示：

import tkinter as tk
import math
import time

class CompassClock:
    def __init__(self, root):
        self.root = root
        self.root.resizable(width=False, height=False)
        self.root.attributes('-topmost', True)
        self.root.overrideredirect(True)

        self.width = 200
        self.height = 200
        self.canvas = tk.Canvas(self.root, width=self.width, height=self.height)
        self.canvas.pack()

        self.draw_compass()

        self.update_clock()

    def draw_compass(self):
        cx = self.width // 2
        cy = self.height // 2
        r = min(cx, cy) - 10

        self.canvas.create_oval(cx-r, cy-r, cx+r, cy+r, width=2)

        for i in range(0, 360, 30):
            x1 = cx + r * math.sin(math.radians(i))
            y1 = cy - r * math.cos(math.radians(i))
            x2 = cx + (r-10) * math.sin(math.radians(i))
            y2 = cy - (r-10) * math.cos(math.radians(i))
            self.canvas.create_line(x1, y1, x2, y2, width=2)

        self.hour_hand = self.canvas.create_line(cx, cy, cx, cy-r//2, width=3, fill='red')
        self.minute_hand = self.canvas.create_line(cx, cy, cx, cy-r*3//4, width=2, fill='blue')
        self.second_hand = self.canvas.create_line(cx, cy, cx, cy-r*3//4, width=1, fill='green')

    def update_clock(self):
        current_time = time.localtime()
        hour = current_time.tm_hour % 12
        minute = current_time.tm_min
        second = current_time.tm_sec

        hour_angle = (hour * 30) + (minute / 2)
        minute_angle = minute * 6
        second_angle = second * 6

        self.canvas.delete(self.hour_hand)
        self.canvas.delete(self.minute_hand)
        self.canvas.delete(self.second_hand)

        cx = self.width // 2
        cy = self.height // 2
        r = min(cx, cy) - 10

        x1 = cx + (r-20) * math.sin(math.radians(hour_angle))
        y1 = cy - (r-20) * math.cos(math.radians(hour_angle))
        self.hour_hand = self.canvas.create_line(cx, cy, x1, y1, width=3, fill='red')

        x2 = cx + (r-10) * math.sin(math.radians(minute_angle))
        y2 = cy - (r-10) * math.cos(math.radians(minute_angle))
        self.minute_hand = self.canvas.create_line(cx, cy, x2, y2, width=2, fill='blue')

        x3 = cx + r * math.sin(math.radians(second_angle))
        y3 = cy - r * math.cos(math.radians(second_angle))
        self.second_hand = self.canvas.create_line(cx, cy, x3, y3, width=1, fill='green')

        self.root.after(1000, self.update_clock)


if __name__ == '__main__':
    root = tk.Tk()
    clock = CompassClock(root)
    root.mainloop()

将此代码保存为.py文件，然后运行即可在电脑桌面上展示罗盘时钟。
