hi
thanks every body for the help.

Now how can check whtr the row am reading is the last row or not??

for example for this below data in csv file

CompName,IpAddr,MacAddr
 XXX,192.178.23.11,78.23.34.23.12
 YYY,192.189.22.11,89.23.43.12.34
 ZZZ,192.179.24.45,89.23.34.12.45

file = open ('C:\some.csv','r')
reader = csv.reader(file)
for row in reader:
      print row
      HERE HOW CAN I CHECK WHTR THIS ROW IS THE LAST ONE IN THE FILE

so that if at all i dint find what am searching for i can write that
information at the last row, after opening the file in a "append" mode.

thanks again for help

regards
yogi
