Unzip zip files in folders and subfolders with python

问题

I try to unzip 150 zip files. All the zip files as different names, and they all spread in one big folder that divided to a lot of sub folders and sub sub folders.i want to extract each archive to separate folder with the same name as the original zip file name and also in the same place as the original zip file . my code is:

import zipfile    
import os,os.path,sys  

pattern = '*.zip'  
folder = r"C:\Project\layers"   
files_process = []  
for root,dirs,files in os.walk(r"C:\Project\layers"):  
    for filenames in files:  
        if filenames == pattern:  
            files_process.append(os.path.join(root, filenames))  
            zip.extract()

After i run the code nothing happened. Thanks in advance for any help on this.

UPDATE:

Finally, this code worked for me:

import zipfile,fnmatch,os

rootPath = r"C:\Project"
pattern = '*.zip'
for root, dirs, files in os.walk(rootPath):
    for filename in fnmatch.filter(files, pattern):
        print(os.path.join(root, filename))
        zipfile.ZipFile(os.path.join(root, filename)).extractall(os.path.join(root, os.path.splitext(filename)[0]))

You could use Path.rglob() to enumerate zip-files recursively and shutil.unpack_archive() to unpack zip files:

#!/usr/bin/env python3
import logging
from pathlib import Path
from shutil import unpack_archive

zip_files = Path(r"C:\Project\layers").rglob("*.zip")
while True:
    try:
        path = next(zip_files)
    except StopIteration:
        break # no more files
    except PermissionError:
        logging.exception("permission error")
    else:
         extract_dir = path.with_name(path.stem)
         unpack_archive(str(path), str(extract_dir), 'zip')

It "extract[s] each archive to separate folder with the same name as the original zip file name and also in the same place as the original zip file" e.g., it extracts 'layers/dir/file.zip' archive into 'layers/dir/file' directory.

To unzip all the files into a temporary folder (Ubuntu)

import tempfile
import zipfile

tmpdirname = tempfile.mkdtemp()

zf = zipfile.ZipFile('/path/to/zipfile.zip')

for fn in zf.namelist():
    temp_file = tmpdirname+"/"+fn
    #print(temp_file)

    f = open(temp_file, 'w')
    f.write(zf.read(fn).decode('utf-8'))
    f.close()
