I was trying to pull duplicates out of 2 different files. Needless to say there are duplicates I would place a # next to the duplicate. Example files: file 1: file 2: 433.3 947.3 543.1 749.0 741.1 859.2 238.5 433.3 839.2 229.1 583.6 990.1 863.4 741.1 859.2 101.8 import string i=1 primaryfile = open('/tmp/extract','r') secondaryfile = open('/tmp/unload') for line in primaryfile: pcompare = line print(pcompare) for row in secondaryfile: i = i + 1 print(i) scompare = row if pcompare == scompare: print(scompare) secondaryfile.write('#') With this code it should go through the files and find a duplicate and place a '#' next to it. But for some reasonson it doesn't even get to the second for statement. I don't know what else to do. Please offer some assistance. :) --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
