Python subprocess run error: 'FileNotFoundError'

I am currently creating an application in python which uses the Youtube Data API and includes the following code block:

import os
from subprocess import run
os.chdir(os.path.dirname(__file__))
command = 'python3.10 uploadYoutube.py --file="blank.mp4" --title="Blank" --description="THIS IS YOUR BLANK VIDEO" --keywords="blank" --category="20" --privacyStatus="private"'
terminal_output = run(command, capture_output=True).stdout 
print(terminal_output)

This produces the error:

    terminal_output = run(command, capture_output=True).stdout
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\subprocess.py", line 503, in run
    with Popen(*popenargs, **kwargs) as process:
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\subprocess.py", line 971, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\subprocess.py", line 1456, in _execute_child
    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

Does anybody know how I could fix this error?

Solution

as Adon Bilivit stated, this is due to the first argument you pass to the command subprocess.run.

As stated in the subprocess documentation, when you provide a string there is a platform dependent interpretation. On POSIX, providing a string

is interpreted as the name or path of the program to execute.

Solution

The first solution is to pass a sequence to the first subprocess.run argument

subprocess.run(command.split(), capture_output=True)

You can also, as the documentation suggests, set shell to True.

If shell is True, it is recommended to pass args as a string rather than as a sequence.

subprocess.run(command, capture_output=True, shell=True)
