pythonでパスワード付きのzipファイルを展開する

Pythonでパスワード付きのzipファイルを解凍する - 珠玉の誤訳
のpython3版

import zipfile

def unzip_with_pwd(filename, path='.', pwd=b''):
    with zipfile.ZipFile(filename, 'r') as zip_file:
        try:
            zip_file.extractall(path=path, pwd=pwd)
            print('extraction is successful!')
        except RuntimeError:
            print('{} is wrong password!'.format(pwd))

if __name__ == "__main__":
    unzip_with_pwd(filename="test.zip", pwd=b'nya')

Windowsで圧縮していると展開したファイルがLinux上で化けるので変換が必要

import zipfile

def unzip_with_pwd_ja(filename, path='.', pwd=b''):
    with zipfile.ZipFile(filename, 'r') as zip_file:
        try:
            for info in zip_file.infolist():
                info.filename = info.filename.encode('cp437').decode('cp932')
                zip_file.extract(info, path=path, pwd=pwd)
            print('extraction is successful!')
        except RuntimeError:
            print('{} is wrong password!'.format(pwd))

if __name__ == "__main__":
    unzip_with_pwd_ja(filename="test.zip", pwd=b'nya')
