Python 如何解壓縮帶密碼的RAR文件

import rarfile

data_file_path = ‘C:\\data_folder\\file_name.rar’
extracted_folder = ‘C:\\TEMP’

rf = rarfile.RarFile(data_file_path)  # 待解壓文件

password = '123456'

rf.setpassword(pwd=password)

rf.extractall(extracted_folder)

如果出現報錯： 

rarfile.RarCannotExec: Cannot find working tool.

把winrar的目錄設置到環境變量，重啟PyCharm 就可以解決。
