Give permission to shell to execute cmd command-CodePudding

I changed the permission for the virtual environment to read-only.

VENV_NAME = '._venv'

drive_path = Path(settings.BASE_DIR).drive

def change_permissions_recursive(path, mode):
    for root, dirs, files in os.walk(path, topdown=False):
        for dir in [os.path.join(root,d) for d in dirs]:
            os.chmod(dir, mode)
            print(dir, "change successfully")
    for file in [os.path.join(root, f) for f in files]:
            os.chmod(file, mode)
            print(file, "change successfully")
change_permissions_recursive(f'{drive_path}/home/{VENV_NAME}', stat.S_IRUSR | stat.S_IRGRP | stat.S_IROTH)

Now I want to run the python code

import subprocess
subprocess.run("dir")

But, this gives me errors like PermissionError and FileNotFoundError.

I do all the venv files permission because shutil can delete this folder and I want to protect this folder. So anybody can tell me any other way to protect this venv from other users or to execute cmd commands using subporcess.

When you are working on file permissions (like making files read-only), the clue generally is not the content of your script, but the way you run it, which, in its turn, depends on your platform:

Windows: run your script/program as administrator (right-click and choose that option)
Linux/UNIX: run your script/program, using sudo.

Change the virtual environment to read & write before executing that python code, and then change it back.
