Python on WAMP: Error When Trying to Run .py Script

I'm trying to test a Python script on WAMP.  I have a working WAMP installation, and followed instructions to add Python (on this page: http://www.mplstutorial.com/wamp_python/python_wamp.html ), except that everything is on the D: drive.  I also restarted the WAMP Server.  
      This error appears when I try to run a page with the .py extension:

  Mod_python error: "PythonHandler default"

  Traceback (most recent call last):

  File "D:\Python24\Lib\site-packages\mod_python\apache.py", line 287, in HandlerDispatch
    log=debug)

  File "D:\Python24\Lib\site-packages\mod_python\apache.py", line 461, in import_module
    f, p, d = imp.find_module(parts[i], path)

   ImportError: No module named default

Saying "PythonHandler default" means "I want all requests to be handled by default.py".  If you have no default.py, you'll get that ImportError.

If you've taken the exact httpd.conf from that "Running Python with WAMP5" page, it's configured for requests for "index.py" and "xa.py" to be handled by those files, and for all other requests to be handled by default.py.  (See the section <Directory "C:/wamp/www/"> in httpd.conf)

If you want a URL like "http://myserver/mymodule.py" to run mymodule.py, you need to use mod_python's CGI Handler: "PythonHandler mod_python.cgihandler"

See http://www.modpython.org/live/current/doc-html/hand-cgi.html for the CGI Handler documentation.

RichieHindle,
   Thanks. I'm just trying to run a script like HelloWorld.py in my www directory.  

Then I put the .htaccess file in the   www  directory, with:
     SetHandler mod_python
     PythonHandler mod_python.cgihandler
as recommended on the modpython page, then restarted the server.
    The error messages went away.  But now only a blank screen appears; it does not print anything to the browser.  (However, the HelloWorld.py script *does* run from the command line.)

I tried the bang line as:
     #!/usr/bin/python
and also as:
    #!D:\Python24
but either way, the script will not run properly when called from the url like
     http://localhost/HelloWorld.py

 What could be wrong?

The shebang line should probably be:

#!D:\Python24\python.exe

but that shouldn't matter for mod_python.

Try this HelloWorld.py:

#!D:\Python24\python.exe
print "Content-Type: text/plain\n\n"
print "Hello, World!\n"

Yes, that worked, even without the   .exe  
  Looks like the problem was, I forgot the header
         print "Content-Type: text/plain\n\n"

So, overall, the problems were the   .htaccess  statements and the content-type header.

It seems to be working now. Thanks!

RichieHindle,
   If you happen to see this, even though it's PAQ'd, I discovered an unintended problem with the .htaccess file:  when it is in my   www  directory, Python files will run, but html files treated as if not even there.  So I had to delete or comment-out the .htaccess statements just to be able to view  html  files on localhost again.
    Maybe the statements in .htaccess can be modified to allow both kinds of files to work simultaneously?  Thanks.
