Sounds like a good plan to me. Something like this would work: py> import difflib py> a = '1728.HK 1033.HK 2393.HK 0968.HK 3378.HK'.split() py> b = '1728.HK 1036.HK 2393.HK 0968.HK 2784.HK 3378.HK'.split() py> print '\n'.join(difflib.unified_diff(a, b)) --- +++ @@ -1,5 +1,6 @@ 1728.HK -1033.HK +1036.HK 2393.HK 0968.HK +2784.HK 3378.HK Obviously you don't type in the strings '1728.HK...', you read them from the files you wish to compare. -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
