[issue13582] IDLE and pythonw.exe stderr problem

[Terry J. Reedy]

Terry J. Reedy added the comment:

Print in the user process goes to shell window. You need to stimulate (or just add) print or warn in the idle process, which normally goes to console, or nowhere. It is hard (intentionally, I am sure) to dynamically manipulate idle process code. Roger said "try adding a "raise Exception" to a constructor for one of the extensions". I would start with a warning in PyShell. See doc or test_warnings for an example warnings call.
