How to Recursively Unzip Nested ZIP Files with Python

1. Introduction

Hello, I am a Python enthusiast. Recently a member asked how to unzip multiple zip files where the extracted files also contain zip files, and how to set up logic to recursively unzip them.

2. Implementation

The following Python code demonstrates a recursive unzip function that handles both zip files and directories.

# -*- coding: utf-8 -*-
import zipfile
import os

def unzip_file(path):
    '''解压zip包'''
    if os.path.exists(path):
        if path.endswith('.zip'):
            z = zipfile.ZipFile(path, 'r')
            unzip_path = os.path.split(path)[0]
            z.extractall(path=unzip_path)
            zip_list = z.namelist()  # 返回解压后的所有文件夹和文件
            for zip_file in zip_list:
                new_path = os.path.join(unzip_path, zip_file)
                unzip_file(new_path)
            z.close()
        elif os.path.isdir(path):
            for file_name in os.listdir(path):
                unzip_file(os.path.join(path, file_name))
    else:
        print('the path is not exist!!!')

if __name__ == '__main__':
    zip_path = r'C:\Users\Desktop\aa\A.zip'
    unzip_file(zip_path)

3. Conclusion

The script provides a practical solution for Python automation tasks involving nested zip archives, helping users resolve similar problems efficiently.

When asking for help, share sanitized demo data, include the relevant code snippet, and attach error screenshots; for longer scripts, attach the .py file.
