python - Data Appending issue -

i trying add combination of words in existing string using python. achieve have written below code.

import subprocess subprocess import popen, pipe  cat = subprocess.popen(["hadoop", "fs", "-cat", "/user/cloudera/rank_t/*"], stdout=subprocess.pipe) dumpoff = popen(["hadoop", "fs", "-put", "-", "/user/cloudera/data"],stdin=pipe) obrind = "0" line1 = "" line in cat.stdout:     runnno= line.split('|')[0]     code = line.split('|')[1]     idval = line.split('|')[2]      if (code == "obr"):         obrind = runnno     line =line + "|"+"obr_"+obrind       dumpoff.stdin.write(line)     print(line) 

my sample data:

1|orc||4002c3|4002c3||||||20141231|||1962 2|obr|1||4002c3|197 hp, rx 16/l|||20141|20141||||||||196248||rj||3711028|||||f 3|obx|1|st|2263||negative intraepithelial l.||||||f|||20141231|rj @#l 4|nte|1|l|negative intraepithelial lesion , . 5|obx|2|st|1158||nil||||||f|||20141231|rj@#l 

expected output:

1|orc||4002c3|4002c3||||||20141231|||1962| 2|obr|1||4002c3|197 hp, rx 16/l|||20141|20141||||||||196248||rj||3711028|||||f|obr_1 3|obx|1|st|2263||negative intraepithelial l.||||||f|||20141231|rj @#l|obr_1 4|nte|1|l|negative intraepithelial lesion , .|obr_1 5|obx|2|st|1158||nil||||||f|||20141231|rj@#l|obr_1 

actual output:

    1|orc||4002c3|4002c3||||||20141231|||1962|     2|obr|1||4002c3|197 hp, rx 16/l|||20141|20141||||||||196248||rj||3711028|||||f     |obr_1     3|obx|1|st|2263||negative intraepithelial l.||||||f|||20141231|rj @#l     |obr_1     4|nte|1|l|negative intraepithelial lesion , .     |obr_1     5|obx|2|st|1158||nil||||||f|||20141231|rj@#l     |obr_1 

the word trying append appending in new line want appending in same line. doing wrong ?

that's because each line has \n @ end. can strip string .strip():

line = line.strip() + "|"+"obr_"+obrind   

or

line = line.strip('\n') + "|"+"obr_"+obrind   

if care white spaces @ begining/end of line.
