请示例代码：用python完成以下需求：截图当前屏幕并把截图名称命名为‘Tessellation’后将此截图插入DSTRESSTOOLGPU_Caps_Viewerbenchmark2023 acer video performance_test_criteria_V10_20220928xls的H20212223格内

您可以使用pyautogui库来实现截图和插入截图的需求。下面是一个示例代码：

import pyautogui
import os

# 截图当前屏幕
screenshot = pyautogui.screenshot()

# 定义截图保存路径和文件名
screenshot_path = "D:\STRESSTOOL\GPU_Caps_Viewer\benchmark"
screenshot_name = "Tessellation.png"

# 保存截图
screenshot.save(os.path.join(screenshot_path, screenshot_name))

# 导入所需的库
import openpyxl
from openpyxl.drawing.image import Image

# 打开Excel文件
excel_file = "D:\STRESSTOOL\GPU_Caps_Viewer\benchmark\2023 acer video performance_test_criteria_V1.0_20220928.xls"
workbook = openpyxl.load_workbook(excel_file)

# 获取指定工作表
worksheet = workbook.active

# 定义要插入截图的单元格范围
cell_range = ["H20", "H21", "H22", "H23"]

# 逐个插入截图
for cell in cell_range:
    # 获取单元格
    target_cell = worksheet[cell]
    
    # 加载截图
    image = Image(os.path.join(screenshot_path, screenshot_name))
    
    # 调整截图大小以适应单元格
    image.width = target_cell.width
    image.height = target_cell.height
    
    # 将截图插入单元格
    target_cell.value = ""
    target_cell.alignment = openpyxl.styles.Alignment(horizontal="center", vertical="center")
    target_cell._comment = openpyxl.comments.Comment("截图", "Python Assistant")
    target_cell.fill = openpyxl.styles.PatternFill(fill_type="solid", fgColor="D9D9D9")
    target_cell.anchor = cell
    worksheet.add_image(image, cell)
    
# 保存Excel文件
workbook.save(excel_file)

请确保在运行代码之前已经安装了pyautogui和openpyxl库。您可以使用以下命令来安装这两个库：

pip install pyautogui openpyxl

请注意，您需要根据您的实际文件路径和单元格范围进行相应的调整
