The problem arises because self.archive_path is a pandas DataFrame and when you try to create a ZipFile object using it, Python throws an error. To fix this issue, you should create a new variable to hold the path to your .zip file. Here’s how you can modify the code: input_path = "//wsl$/Ubuntu-20.04/home/melissachua/CODEX/input_data" # Open all the subfolders within path for root, dirs, files in os.walk(input_path): for file in files: zip_file_path = os.

Calculating Available Sessions for Appointment Booking without Using a Loop or Cursor Introduction The problem of calculating available sessions for appointment booking is a classic example of a scheduling problem.
