Python批量解压zip文件

import os
import shutil
import zipfile

parent_path=r‘G:\DEM\NASADEM-中国‘ #父文件夹路径
directory_to_extract_to=r"G:\DEM\ALL" #解压目标文件夹路径
for root, dirs, files in os.walk(parent_path):
      # 读取文件名
    for name in files:
        print(name)
        path_to_zip_file=root+‘\\‘+name
        print(path_to_zip_file)
        with zipfile.ZipFile(path_to_zip_file, ‘r‘) as zip_ref:
            zip_ref.extractall(directory_to_extract_to)
