Thanks for your help. I will do my best for the forum :)

I advanced a little bit with the algorithm and at least I can now
extract and compare the fields :)
For my beginner skills I think this is too much for me. Now next step
is to add the second field with the number to the Namelist and copy it
to a third filename I suppose.

import csv

origf = open('c:/Working/Test_phonebook.csv', 'rt')
secfile = open('c:/Working/phones.csv', 'rt')

phonelist = []
namelist = []

names = csv.reader(origf, delimiter=';')
phones = csv.reader(secfile, delimiter=';')
for tel in phones:

#print "*"*25,phonelist,"*"*25
rows = 0

def finder(name_row):
    for ex_phone in phonelist:
#        phonelist.append(tel)
        telstr = ex_phone[0].lower()
#        print "*"*25 + " I got %s" % telstr
#        print "\nGot name from Name_Find :%s" % name_row
        if telstr.find(name_row) >= 0:
            print "\nName found: %s" % name_row
#            print "\nNot found %s" % name_row

def name_find():

    for row in names:
        name_row = row[0].lower()
#        print "\nExtracted Name is :% s" % name_row
#        name_find()
#    rows = rows +1
