Is it possible to determine, from within Python, whether Python
allocated or inherited the console?
If a console session isn't headless (i.e. it's not a pseudoconsole)
and has a window (i.e. not allocated with CREATE_NO_WINDOW), then the
effective owner of the window is initially the process that allocated
the console session, as long as it's still running and attached. For
example, with "python.exe" (not a launcher) executed from Explorer:
>>> hwnd = win32console.GetConsoleWindow()
>>> tid, pid = win32process.GetWindowThreadProcessId(hwnd)
>>> pid == os.getpid()
True
I can't replicate this. I installed pywin32 in a Python 3.8 virtual
environment, and double-clicked on the venv\Scripts\python.exe in explorer:
Python 3.8.6 (tags/v3.8.6:db45529, Sep 23 2020, 15:52:53) [MSC v.1927 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os, win32console, win32process
>>> hwnd = win32console.GetConsoleWindow()
>>> tid, pid = win32process.GetWindowThreadProcessId(hwnd)
>>> pid == os.getpid()
False
I tried to find out what happens, using your other code:
>>> import win32con, win32api
>>> access = win32con.PROCESS_QUERY_LIMITED_INFORMATION
>>> hproc = win32api.OpenProcess(access, False, pid)
>>> executable = win32process.GetModuleFileNameEx(hproc, None)
>>> print(executable)
C:\Temp\Python\Console\venv\Scripts\python.exe
>>> hproc = win32api.OpenProcess(access, False, os.getpid())
>>> win32process.GetModuleFileNameEx(hproc, None)
'C:\\dev\\Python\\Python38\\python.exe'
So, if I understand this correctly, the console is owned by the venv
Python, but the running process is the installed Python executable. I'm
lost! How did that latter one get involved?

Gertjan.
