How to use Python to connect to a database
Using python, you can connect and run queries against a MySQL database on your server.
In this example, we've created a test script named test_db.py and placed it in our cgi-bin folder. We also updated the file's permissions to 755.
We also used the following settings within the code:
- database name: inmoti6_pytest
- database user: inmoti6_pytest
- database password: pytest
- database host: localhost
We're connecting to the database and running SELECT VERSION(), which shows us which version of MySQL we are running.
AddHandler cgi-script .cgi .pl .py
# connect to the database
db = MySQLdb.connect("localhost","inmoti6_pytest","pytest","inmoti6_pytest" )
# setup a cursor object using cursor() method
cursor = db.cursor()
# run an sql question
# grab one result
data = cursor.fetchone()
# begin printing data to the screen
print "Content-Type: text/html"
<title>Python - Hello World</title>
print "Database version : %s " % data
# close the mysql database connection

Warning for other users on shared hosting (business) servers, as of 9/20/2012 this example appears to be broken due to MySQLdb library not being properly installed for the current version of python in /usr/lib/python2.4/site-packages on shared hosting servers.
Since you won't have SSH access as a business customer (you need to buy VPS or dedicated hosting for ssh access), you will not be able to install the setuptools-0.6c11 and MySQL-python-1.2.3 on your own. And the inMotion support folks said they are unwilling to add MySQLdb to the latest python version library directory on their shared servers.
I would encourage you to ask inMotion tech support to fix the python MySQLdb installation on your shared server. Maybe if enough customers ask for this they will eventually agree to do it.
The work-around that inMotion tech support suggested is to have my python CGI script call another external script (presumably written in PHP or Perl or some other scripting language that is able to access MySQL properly), and have the child script read/write data from/to my database on behalf of the python script. Very messy in my opinion.
I guess I will just stick with PHP or Perl for CGI for now whenever I need to access MySQL database since python is incapable of doing so on our server.

I just responded to your original question with a resolution to your issue. Please check that to see if it will help you.
It seems that some select older servers do not have that module installed. As they are older servers and will likely soon be decommissioned, adding and updating them on the server wide level is not something the Systems team will do.
We can, however, move anyone who encounters this issue to newer servers that do have the capability. The newest servers also run an updated version of Python (2.6) and do have the MySQLdb module installed.
I do apologize for any misinformation you may have gotten with your support ticket. I will take measures to ensure a request of this nature is handled correctly in the future.

Is it possible to get something like bottle installed? I'm looking at bottle as my server engine and would really like to get it working here.

If were only going to be affecting your, it may be possible to run it. But it appears to be more of a server-wide thing, which, since you're on a shared server account-type, is not going to be allowed. If you want to inquire with live support, you can email firstname.lastname@example.org and you'll get a response through email.
If you have any further questions, please contact technical support or leave a comment at the bottom of the page.
