一、添加轮子

1.添加托盘区图标库 infi.systray

from infi.systray import SysTrayIcon

2.添加图像处理库 Pillow

from PIL import Image, ImageDraw, ImageFont

3.添加 psutil 来获取CPU、内存信息

import psutil

二、完整代码

from infi.systray import SysTrayIcon
from PIL import Image, ImageDraw, ImageFont
import time
import psutil

image = "main.ico"
initialStart = True
systray = SysTrayIcon(image, "CPU/MEM")

while True:
    img = Image.new('RGBA', (50, 50), color=(255, 255, 255, 100))
    d = ImageDraw.Draw(img)
    d.rectangle((0, 25, 50, 50), fill=(39, 112, 229), outline=None)

    font_type = ImageFont.truetype("arial.ttf", 25)
    a = psutil.cpu_percent(interval=1, percpu=False)
    b = psutil.virtual_memory().percent
    d.text((0, 0), f"{a}\n{b}", fill=(255, 255, 255), font=font_type)

    img.save(image)

    if initialStart:
        systray.start()
        initialStart = False
    else:
        systray.update(icon=image)
    time.sleep(0.5)

三、实际效果展示
