python crash problem

[Yelena]

Here is the code, I edited out some private info:

import sys
import urllib2
import string
import re
import datetime
from mx import DateTime
from dbfpy import dbf

addylist = ['add.dbf']
okset = ['P','L','I','B']
for addy in addylist:
    db = dbf.Dbf(addy)
    print (addy)
    count = len(db)
    db.close()
    del db
    foo = ((0, 1000),(1000,count/3), (count/3, count/3*2), (count/3*2,
count))
    for (start,finish) in foo:
        ab = dbf.Dbf(addy)
        for x in range(start, finish):
            print x
            rec = ab[x]
            if rec["flag"] in [1,3]:
                INP_info = rec["address"] + " " + rec["city"] + " "
+rec["state"] + " " + rec["zip"]
                INP_info = INP_info.replace(' ',',')
                HOST_URL = '***'
                KEY = '***'
                STD_URL = '***'
                STD_URL = STD_URL.replace('location=','location=' +
INP_info)
                STD_URL = STD_URL.replace('key=','key=' + KEY)
                Addy_INPUT = HOST_URL + STD_URL
                try:
                    for line in urllib2.urlopen(Addy_INPUT):
                        safe = line
                        geoQ = safe.find('\"geocodeQualityCode\"',1)
                        geoCode = safe[(geoQ+22):(geoQ+26)]
                        if geoCode[0] in okset:
                            lat = safe.find('\"lat\":', 1)
                            lng = safe.find('\"lng\":', 1)
                            lngbound = safe.find('\"mapUrl":', 1)
                            zipCode = safe.find('\"postalCode\"', 1)
                            zipbound = safe.find('\"adminArea1\"', 1)
                            rec["lat"] = float(safe[(lat + 6):
(lng-1)])
                            rec["long"] = float(safe[(lng+6):
(lngbound-2)])
                            rec["zip_final"] = safe[(zipCode+14):

                            rec["flag"] = 2
                            print ('ok ')
                        else:
                            rec["flag"] = 5
                except:
                    rec["flag"] = 5
                rec.store()
                del rec
        ab.close()
        del ab
