404 error while executing .py file in cgi-bin using apache2
previously i had error in installing apache2 for python, this is the link
I thought i should continue there but right now i'm getting a new error so posting it as a new one this is what the problem is
I have placed a file hello.py having code
#!/usr/bin/python
print "Content-type:text/html\r\n\r\n"
print '<html>'
print '<head>'
print '<title>Hello Word - First CGI Program</title>'
print '</head>'
print '<body>'
print '<h2>Hello Word! This is my first CGI program</h2>'
print '</body>'
print '</html>'
in a folder /var/www/cgi-bin when I run this on apache2 using
i'm getting this error
The requested URL /cgi-bin/hello.py was not found on this server. Apache/2.2.14(Ubuntu)Server at localhost Port 80
This is the code that i found in the default page in sites-available folder:

Please help me through this.
Answer
In your Apache configuration, you need to change the Directory directive to: <Directory /var/www/cgi-bin> if this is where you intend to host your mod_python scripts.
UPDATE:
You're placing your python script in /var/www/cgi-bin but /cgi-bin/ is defined to point to /usr/lib/cgi-bin. You need to standardize on one location for /cgi-bin/.
Here's what I would propose as your corrected Apache configuration. Note that I didn't remove any lines, I only commented out the lines that are not needed or have been replaced.
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
#<Directory /var/www>
<Directory /var/www/cgi-bin>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
AddHandler mod_python .py
PythonHandler mod_python.publisher
PythonDebug On
</Directory>
#ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
#<Directory "/usr/lib/cgi-bin">
# AllowOverride None
# Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
# Order allow,deny
# Allow from all
#</Directory>
ErrorLog /var/log/apache2/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.

</Directory>
</VirtualHost>
UPDATE 2:
Now that your Apache configuration is correct, and we've verified that your module is importing correctly, you're still getting a 404. This is because you are using the mod_python publisher handler, which expects a different usage than what you have implemented. Basically, you have implemented a simple CGI script that just prints output. mod_python has a specific API for executing your module. You should try this example to get an understanding of how it works.
To implement your test module as a valid mod_python publisher, you could change hello.py to this:
def index(req):
return """<html>
<head>
<title>Hello Word - First CGI Program</title>
</head>
<body>
<h2>Hello Word! This is my first CGI program</h2>
</body>
</html>"""
Note that the reason you were getting a 404 error (even though the module was imported) is explained on this page:
The traversal will stop and HTTP_NOT_FOUND will be returned to the client if:
Any of the traversed object's names begin with an underscore ("_"). Use underscores to protect objects that should not be accessible from the web.
A module is encountered. Published objects cannot be modules for security reasons.
If an object in the path could not be found, HTTP_NOT_FOUND is returned to the client.
