Tim, thank you very much for the reply.  The 'cheetah' function is now
working!

I am still having a problem creating the file.  I continually get
errors.  I am sure that it is something very simple.

Below is the code, please guide me in the right direction.... ::

import psycopg2, psycopg2.extensions
from Cheetah.Template import Template
import operator
import os
from SafetyNet import SafetyNet

filename = open("C:\Python25\Lib\site-packages\PSN
\InstalledDevices.html")

db = psycopg2.connect("dbname='XXX' user='XXX' host='XXX'")

pocmonitors_cur = db.cursor()
pocmonitors_cur.execute("""SELECT pocmonitor_name, pocmonitor_sn FROM
pocmonitor ORDER BY pocmonitor_name""")

pocmonitors = []

for i in range(pocmonitors_cur.rowcount) :
    pocmonitors.append(pocmonitors_cur.fetchone())
pocmonitors_cur.close()
db.close()

total_results = len(pocmonitors)

nameSpace = {'title': 'First Cheetah Example', 'pocmonitors':
pocmonitors, 'total_results': total_results}

output = Template(file='C:\Python25\Lib\site-packages\PSN
\SafetyNet.tmpl', searchList=[nameSpace])

print output


filename.write(output)



Thanks for the help!
