Hi Steven and Peter, Steven: Interestingly (oddly???) enough, the output captured by hooking the cgitb handler on my system appears to be shorter than the default cgitb output. You can see this yourself via this tiny script:
import cgitb cgitb.enable(format='text') x = 1/0 The solution I came up with (Python 3.5.1) was to use your StringIO technique with the Hook's 'file=' parameter. import io cgitb_buffer = io.StringIO() cgitb.Hook(file=cgitb_buffer, format='text) return cgitb_buffer.getvalue() Peter: Your output was helpful in seeing the difference I mentioned above. Thank you both for your help! Malcolm -- https://mail.python.org/mailman/listinfo/python-list
