PermissionError: [WinError 5] Permission denied

Question

i have problem with PermissionError: [WinError 5] permission denied. Can somebody tell my why?

import subprocess

run_shell = subprocess.run(['./', 'ls'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

test = str(run_shell.stdout.decode()).split('\n')

for el in test:
    if not el:
        continue
    print(f"Plik: {el}")
print("Info: {}".format(run_shell.stderr.decode()))

Even if i am trying only with subprocess, I still have it.

import subprocess
subprocess.run(['./', 'ls'])

tried this, doesn't help.

subprocess.run([r'./', 'ls']) 

Error:

Traceback (most recent call last):
  File "c:\Users\gawiq\KodyPython\lekcja_5_8.py", line 4, in <module>

I tried already in CLI with administrator rights: pip install pydirectory, python -m pip install --upgrade pip,

also i tried

pip install --user subprocess.run,

but then, i got this:

Python: 'list' object has no attribute 'read'

Python version 3.10.5 pip version-22.2.1 using Windows 10 Home 64-bit and VSC

Thanks for help

Your problem is probably that neither ls nor ./ is avalid command for the Windows CLI
