TPythonInputOutput separation Python Error

[iqrf 3]

Hello,
is there any way to remap PyErr_Print using a custom function? I would like to log the error output on a separate sheet. Now everything ends up in TPythonInputOutput. Or can it be done differently?
Thanks for the idea.

I think the best you can is to refer to the PythonEngine's DoRedirectIO sources

 

the line

 sys.stdin=sys.stderr=sys.stdout=DebugOutput() 

redirects error output onto PythonEngine.IO

so far you could try to use other redirection somewhere in your code

 

Hope this helps

from io import StringIO
import sys

old_stderr = sys.stderr
sys.stderr = mystderr = StringIO()

# examine mystderr.getvalue()

Thanks, it works.

 try
    MaskFPUExceptions(True);
    PythonEngine1.ExecStrings(Memo1.Lines);

  except
    errorMessage := MainModule.mystderr.getvalue();
    ErrorLog(errorMessage);
  end;

I would just like to continuously catch errors if someone writes in the Python code for example print("Error example 1", file=sys.stderr)
or
sys.stderr.write("Error Example 2")
The current solution only prints everything at once, with the same timestamp.

Thanks.
