python to open dbf?

hi guys, python novice here, thanks for any help....

have this working so far:

import arcgisscripting
import re
import dbfpy
import sqlite3

# create the geoprocessor object
gp = arcgisscripting.create(9.3)

gp.workspace = "I:\PDtest"

layer1 = raw_input('what is layer1?')
layer1 = layer1 + ".shp"
layer2 = raw_input('what is layer2?')
layer2 = layer2 + ".shp"

# process
gp.PointDistance_analysis(layer1,layer2,"temp.dbf","#")

layer1 = re.sub('.shp', '', layer1)
layer2 = re.sub('.shp', '', layer2)

final_layer = layer1+"_"+layer2
complete_name = final_layer+".dbf"
gp.Rename_management("temp.dbf", complete_name)

...it runs a point distance analysis on two layers input by the user, and renames the resulting dbf to a combination of the two layer names. this is pretty basic stuff but I'm new to this; now I want to open that resultant .dbf and use sqlite to interrogate it; I've imported dbfpy but can't seem to get past errors indicating that something is wrong with my dbf syntax....for example...

db = dbf.Dbf(complete_name)
for rec in db:
print rec
print

results in 'name dbf is not defined', and several edits to this result in similar problems; what am I doing wrong when trying to open this .dbf? I seem to have dbfpy in the proper place so that shouldn't be an issue...

thanks very much,

cj
