 If you're the type of programmer who debugs using scattered ``print``
-statements, note that ``print`` statements have no effect in mod_python; they
-don't appear in the Apache log, as one might expect. If you have the need to
-print debugging information in a mod_python setup, either do this::
+statements, note that writing to ``stdout`` with a regular ``print`` statement
+is a bad idea.  Things written in this fashion will not appear in the Apache

+If you have the need to print debugging information in a mod_python setup, you
+have three options.  The first is to print to ``stderr`` explicitly, like so::
 
-Or add the debugging information to the template of your page.
+    print >> sys.stderr, 'debug text'
+    sys.stderr.flush()
+
+Note that ``stderr`` is buffered, so calling ``flush`` is necessary if you wish
+debugging information to be displayed promptly.
+
+A second, more compact approach is to use an assertion::
+
+    assert False, 'debug text'
+
+The third option is to add debugging information to the template of your page.
