使用python删除word文档中的指定段落，顺便实现一下文档中的图片导出

#! /etc/env/bin python3
#! *_* coding=utf8 *_*


from pathlib import Path
from docx import Document
import os

# 从word中导出图片
def extract_img_word(filename='',doc_path=''):

    docx文档其实也是一个zip压缩包，所以我们可以通过zip包解压它
    也可以直接改文件后缀

                zip_file.extract(names, doc_path)
