1) In the mod_python tutorial it says:

-------
2.4 Testing

...
...

2. Add the following Apache directives, which can appear in either the
main server configuration file, or .htaccess. If you are going to be
using the .htaccess file, you will not need the <Directory> tag below
(the directory then becomes the one in which the .htaccess file is
located), ***and you will need to make sure the AllowOverride
directive applicable to this directory has at least FileInfo
specified. (The default is None, which will not work.)****

<Directory /some/directory/htdocs/test>
        AddHandler mod_python .py
        PythonHandler mptest
        PythonDebug On
</Directory>
--------

Note the last sentence in the directions above.  I explain what is
needed for that part at the link in (2) below.  Also note the
directory listed in the opening <Directory> tag:

/some/directory/htdocs/test

That specifies a sub directory of htdocs.  That's because the htdocs
directory has its own <Directory> tag in httpd.conf, which specifies
the things you can to with it.  If you look around in httpd.conf, you
will see the <Directory> tag that applies to htdocs.  Mine looks like
this:

<Directory "/Library/Apache2/htdocs">
...
...
<Directory>

The mod_python Testing tutorial wants you to create your own sub
directory in htdocs, so that you can specify your own rules for that
directory.  You're probably getting errors because you have two
<Directory> tags in your httpd.conf file for the htdocs directory, and
the second tag is overwriting the first one.


2) You can see the latter part of this thread for what I did to get
mptest.py to work:

http://groups.google.com/group/comp.lang.python/browse_thread/thread/3ccaf303b8b4fd31/ea2645ec03370fb2?lnk=gst&q=mod_python&rnum=1#ea2645ec03370fb2


3) I put any <Directory> tags I added to httpd.conf below the first
<Directory> tag in http.conf, which is this one:

<Directory "/Library/Apache2/htdocs">

so that the ones lower down in the file will override the previous
tags if there is a conflict.
