Это мой код.Я получаю сообщение об ошибке при попытке выполнить этот скрипт
Error raise BadZipFile("File is not a zip file")
BadZipFile: File is not a zip file
Это мой исходный путь к каталогу
data_dir = r'L: \ DataQA \ Python Unzip Files \ Source Zipped '
У меня есть несколько заархивированных папок в папке «Source Zipped» (без сжатия).Тот же код работает, когда я заархивирую все подпапки исходного Zip в одну папку Zip.Но я не хочу такой подход.
