How to call script with python in the same directory with subprocesses?

Question

I'm trying to open a script from the same directory with subprocesses with python 3 in Windows 10,(I Am the administrator) and using pycharm, however I'm getting the following errors for any alternative solution I try:

Here is my code:

import subprocess
subprocess.call(['C:\\Users\\CobraCommander\\PycharmProjects\\BlackBox', 'Avalon.py'])  # The above "BlackBox" it's the directory for both files.

with this I get the following error:

PermissionError: [WinError 5] Access is denied

If I try instead:

subprocess.call(['python Avalon.py'])

with this I get the following error:

FileNotFoundError: [WinError 2] The system cannot find the file specified

so I tried:

subprocess.call(['C:\\Users\\CobraCommander\\PycharmProjects\\BlackBox\\Avalon.py'])

with this I get the following error:

OSError: [WinError 193] %1 is not a valid Win32 application

I also tried to run as administrator from terminal and get same error:

PermissionError: [WinError 5] Access is denied

Kindly before trying to mark as duplicate, note that I have already read the other posts for the errors as well as subprocesses.

Can anybody advise how to lunch this script in python from another script?

Add python before your script so instead of

subprocess.call(['C:\\Users\\CobraCommander\\PycharmProjects\\BlackBox\\Avalon.py'])

use

subprocess.call(['python', 'C:\\Users\\CobraCommander\\PycharmProjects\\BlackBox\\Avalon.py'])

Make sure your PYTHONPATH environment variable is set.

You need to supply cwd argument to set the working directory:

https://docs.python.org/3/library/subprocess.html#subprocess.call

import subprocess

if __name__ == '__main__':
    subprocess.run(r'touch d:\test.txt')
    p = subprocess.run(r'ls -la test.txt', cwd=r'd:\\', stdout=subprocess.PIPE)
    print(p.stdout.decode())

output:
