Thanks. If the file content were to be scrambled a bit (say, like 0005.hk shows up first in the file), should that affect the answer you want? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

As Dave already mentioned you need to split on whitespace:
>>> file_contentsA = "0001.hk 0002.hk 0003.hk"
>>> file_contentsA.split()
['0001.hk', '0002.hk', '0003.hk']
The easiest way to get the added/removed entries is set arithmetic:
>>> file_contentsB = "0001.hk 0002.hk 0005.hk 0006.hk"
>>> entriesA = set(file_contentsA.split())
>>> entriesB = set(file_contentsB.split())
>>> entriesA - entriesB # removed items:
{'0003.hk'}
>>> entriesB - entriesA # added items:
{'0005.hk', '0006.hk'}
Now let's work on the output format:
>>> added = entriesB - entriesA
>>> removed = entriesA - entriesB
>>> added_or_removed = added | removed # union of both sets
>>> for entry in sorted(added_or_removed):
... if entry in added:
... print("+" + entry)
... else:
... print("-" + entry)
...
-0003.hk
+0005.hk
+0006.hk
Limitations of this approach:
- information about duplicate entries is lost
- the original order of entries is lost

There are lots of beginners tutorials on the web. This page lists some. https://wiki.python.org/moin/BeginnersGuide/NonProgrammers Which one suits you best depends on your own style and background. The best thing is to try a couple and see what feels like the best fit for you. If you get stuck ask questions here. We like to know: The OS and Python version you use A full listing of any error messages A listing of the code resulting in the error.
