在Python中，将多个文件夹(在目录中)压缩到单个文件(在新目录中

import os
import zipfile

def zip_folders(folders, zip_filename):
    with zipfile.ZipFile(zip_filename, 'w', zipfile.ZIP_DEFLATED) as zipf:
        for folder in folders:
            for root, dirs, files in os.walk(folder):
                for file in files:
                    # 获取文件的相对路径
                    relative_path = os.path.relpath(os.path.join(root, file), folder)
                    # 将文件添加到zip文件中
                    zipf.write(os.path.join(root, file), relative_path)

# 要压缩的文件夹列表
folders_to_zip = ['folder1', 'folder2', 'folder3']
# 压缩后的文件名
zip_filename = 'compressed.zip'

# 执行压缩
zip_folders(folders_to_zip, zip_filename)
