python解压缩文件或文件夹两种常见方式(附代码)

import os
import zipfile

def compress_folder_to_zip(folder_path, zip_path):
    with zipfile.ZipFile(zip_path, 'w', zipfile.ZIP_DEFLATED) as zipf:
        for root, dirs, files in os.walk(folder_path):
            for file in files:
                file_path = os.path.join(root, file)
                # 添加到 ZIP 文件时，保留相对路径
                arcname = os.path.relpath(file_path, folder_path)
                zipf.write(file_path, arcname)
    print(f"压缩完成：{zip_path}")

# 示例用法
compress_folder_to_zip('path/to/folder', 'output.zip')

import shutil

def compress_with_shutil(folder_path, output_path, format='zip'):
    # format 支持 "zip", "tar", "gztar", "bztar", "xztar"
    shutil.make_archive(output_path, format, folder_path)
    print(f"压缩完成：{output_path}.{format}")

# 示例用法
compress_with_shutil('path/to/folder', 'output', 'zip')

import zipfile

def extract_zip(zip_path, extract_to):
    with zipfile.ZipFile(zip_path, 'r') as zipf:
        zipf.extractall(extract_to)
    print(f"解压完成：{extract_to}")

# 示例用法
extract_zip('output.zip', 'path/to/extract')

import shutil

def extract_with_shutil(zip_path, extract_to):
    shutil.unpack_archive(zip_path, extract_to)
    print(f"解压完成：{extract_to}")

# 示例用法
extract_with_shutil('output.zip', 'path/to/extract')

import os
import zipfile
import shutil

def compress_folder(folder_path, zip_path):
    with zipfile.ZipFile(zip_path, 'w', zipfile.ZIP_DEFLATED) as zipf:
        for root, dirs, files in os.walk(folder_path):
            for file in files:
                file_path = os.path.join(root, file)
                arcname = os.path.relpath(file_path, folder_path)
                zipf.write(file_path, arcname)
    print(f"压缩完成：{zip_path}")

def decompress_folder(zip_path, extract_to):
    with zipfile.ZipFile(zip_path, 'r') as zipf:
        zipf.extractall(extract_to)
    print(f"解压完成：{extract_to}")

# 示例用法
if __name__ == "__main__":
    # 压缩文件夹
    compress_folder('path/to/folder', 'output.zip')
    # 解压 ZIP 文件
    decompress_folder('output.zip', 'path/to/extract')
