You may, but that doesn't change the fact that Rhodri's post is 100%
accurate.

Unless you're talking about an implementation of a console or terminal
emulator in tkinter, this is incorrect.  Tkinter does not do anything
with standard out.

I guess things keep going in circles because people are just trying to
help you understand what these various parts of the system are and how
they fit together, particularly with regards to so-called "console
applications."  (Text-mode, terminal-based, etc.)

Other than a pre-arranged protocol (win32 console api, ANSI, VT100, or
similar) between the displayer of the bytes and the python program, code
does not in fact have power to control what happens in the "console."

This is just the terminal emulator trying to be smart and assuming
meaning in the bytes given to it, which may be a valid assumption on its
part, or may  not.  This is no way implies that all terminal emulators
should do this, nor do most terminal emulators.

Your initial query back in the beginning did not state this.  Indeed you
never stated which console you wanted to work with. We addressed several
common ones including the Win32 console window (which cmd.exe runs in)
and various terminal emulators.

I read frustration in several posts, but never reviling!

The PyCharm developers built their own window to display "console"
output (standard-out bytes) from the app, and they could have their own
window interpret bytes and messages however they wanted to, and added
their own PyCharm-specific feature including hot links to error
locations (I think that comes from standard-err, though, not
standard-out). So if you want the PyCharm output window to create a
clickable hot-link for you you have to modify the PyCharm code to do that.

Not sure what you mean by that?
