Issue using replace function in python

I am trying to encrypt a word and than replace it in the given text for that i am using replace() in python. This method is able to replace the word but keeps the original one in the text also. Below is my code

import subprocess
import bz2
import base64
from subprocess import Popen, PIPE

cat = subprocess.Popen(["hadoop", "fs", "-cat", "/user/cloudera/xxx.dat"], stdout=subprocess.PIPE)
for line in cat.stdout:
    code = line.split('|')[0]
    if (code == "ID"):
        name = line.split('|')[5]
        address = line.split('|')[11]
        ciphername = base64.b64encode(bz2.compress(name))
        cipheraddr = base64.b64encode(bz2.compress(address))
        line.replace(name,ciphername).replace(address,cipheraddr)
        print line

Sample:

ID|1|ZXD0629|ZXD0629||HODJON||11383129|M|||221 B POLLARD RD��KAsODK�TBN�37764|||||||629Z800060|480837

Output:

'ID|1|ZXD0629|ZXD0629||QlpoOTFBWSZTWbk9uLgAAAIGCAbRiAACACAAMQZMQQaMItAUVNzxdyRThQkLk9uLgA==||11383129|M|||QlpoOTFBWSZTWT0tjHQAAAQeCEAALeAkDdQAAgAgADFNMjExMQpo0ZqBmowcuKOA3JhB1VMGcoxTGvi7kinChIHpbGOg|||||||QlpoOTFBWSZTWc5EbhIAAAQKAFNgABAgACEpppkIYBoRvMsvi7kinChIZyI3CQA=|480837\n'

Expected Output:

ID|1|ZXD0629|ZXD0629||QlpoOTFBWSZTWbk9uLgAAAIGCAbRiAACACAAMQZMQQaMItAUVNzxdyRThQkLk9uLgA==||11383129|M|||QlpoOTFBWSZTWT0tjHQAAAQeCEAALeAkDdQAAgAgADFNMjExMQpo0ZqBmowcuKOA3JhB1VMGcoxTGvi7kinChIHpbGOg|||||||QlpoOTFBWSZTWc5EbhIAAAQKAFNgABAgACEpppkIYBoRvMsvi7kinChIZyI3CQA=|480837\n

I don't need the original text without encryption i only need the encrypted one in my text. I have huge records so i cannot post entire sample here that's why i have posted a small sample. I don't know this issue is because of replace() or some mistake i did while implementing. Please help

Wheb calling str.replace() you don't change the original string value, the replace() function returns new value, so here you need to rewrite your original string with the replaced one:

line = line.replace(name,ciphername).replace(address,cipheraddr)
print line
