尝试关闭窗口的Python中的权限被拒绝错误

Question

I'm trying to close an open TextEdit window using Python. I can open the window just fine using:

import subprocess
p = subprocess.call(['open', 'allen_grammar.txt'])

But when I try to close the window using

p = subprocess.Popen( 'allen_grammar.txt')
p.terminate()

I get a permission denied error:

p = subprocess.Popen( 'allen_grammar.txt')
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 707, in __init__
    restore_signals, start_new_session)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 1326, in _execute_child
    raise child_exception_type(errno_num, err_msg)
PermissionError: [Errno 13] Permission denied

I have full permissions on the file and I'm the admin of the computer.

Answer 1

The call to Popen should be like this:

    p = subprocess.Popen(['notepad.exe','allen_grammar.txt'])

I've used notepad since I don't have TextEdit, you can replace 'notepad.exe' in the call to whatever text editor you want, p.terminate() should work fine afterwards

Not really an answer but a successful workaround. I had to use Applescript and calling Applescript from Python goes like this:

os.system(f'''/usr/bin/osascript -e 'tell app "TextEdit" to close (every window whose name is "allen_grammar.txt")' ''')
