Python实现读取excel中的图片功能

pip install openpyxl

pip install pyzbar
pip install pillow
pip install numpy

from openpyxl import load_workbook
# 加载excel
wb = load_workbook("111.xlsx")
# 切换到第一张表
ws = wb[wb.sheetnames[0]]
# 获取A3单元
cell = ws['A3']
# 输出A3单元的值
print(cell.value)

import os
from zipfile import ZipFile
# 解压目录
unzip_path = "./unzip"
if not os.path.exists(unzip_path):

    for file in f.namelist():
        # 解压图片部分的文件

from openpyxl import load_workbook

# 遍历表中所有托
for image in ws._images:

<openpyxl.drawing.spreadsheet_drawing.AnchorMarker object>
Parameters:
col=0, colOff=1, row=0, rowOff=1
