Python递归解压缩多级.zip压缩包

参考如下代码（from:https://stackoverflow.com/questions/36285502/how-to-extract-zip-file-recursively-in-python）：

import os
import io
import zipfile

def extract(filename):
    z = zipfile.ZipFile(filename)
    for f in z.namelist():
        # get directory name from file
        dirname = os.path.splitext(f)[0]  
        # create new directory
        os.mkdir(dirname)  
        # read inner zip file into bytes buffer 
        content = io.BytesIO(z.read(f))
        zip_file = zipfile.ZipFile(content)
        for i in zip_file.namelist():
            zip_file.extract(i, dirname)

封装到class

import os
import shutil
from BetaLogAnalysis.settings import ZIP_FILES_DIR, EXTRACT_DIR


class ExtractArchive(object):
    """ 递归解压缩.zip文件"""

    def __init__(self, zip_file_dir, extract_dir):
        """
             @zip_file_dir: .zip格式的压缩包文件所在目录
             @extract_dir: name.zip文件将被提取到extract/name
        """
        self.zip_file_dir = zip_file_dir
        self.extract_dir = extract_dir

    def run(self):
        for root, dirs, files in os.walk(self.zip_file_dir):
            for filename in files:
                if filename.endswith(".zip"):
                    # 创建跟压缩包同名的文件夹
                    os.mkdir(os.path.join(self.extract_dir, filename[:-4]))
                    zip_file = os.path.join(self.zip_file_dir, filename)
                    to_folder = os.path.join(self.extract_dir, filename[:-4])
                    self.extract_zip(zip_file, to_folder)

    def extract_zip(self, zip_file, to_folder):
        """  递归地提取格式为.zip的压缩包内的所有文件并在提
             取后将原文件删除

             @zip_file: .zip格式的压缩包文件
             @to_folder: 将文件提取到此处
        """
        # 解压
        shutil.unpack_archive(zip_file, to_folder)
        # 将原文件删除
        os.remove(zip_file)
        # 遍历 to_folder
        for root, dirs, files in os.walk(to_folder):
            for filename in files:
                if filename.endswith(".zip"):
                    os.mkdir(os.path.join(to_folder, filename[:-4]))
                    to_folder = os.path.join(to_folder, filename[:-4])
                    zip_file = os.path.join(root, filename)
                    self.extract_zip(zip_file, to_folder)


if __name__ == '__main__':
    e = ExtractArchive(ZIP_FILES_DIR, EXTRACT_DIR)
    e.run()

尚存在的问题：

中文乱码

名字过长报错： FileNotFoundError: [WinError 206] 文件名或扩展名太长。
