help: replace some str.split() calls by str.partition() or str.rpartition()
Since Python 2.5 str has new methods: partition and rpartition. They are more
specialized than the usual split and rsplit, and they sometimes convey the
intent of code better and also are a bit faster (faster than split/rsplit with
maxsplit specified). Let's use them in appropriate places for a small speedup.
Example performance (partition):
$ python -m timeit 'assert "apple|orange|banana".split("|")[0] == "apple"'
1000000 loops, best of 3: 0.376 usec per loop
$ python -m timeit 'assert "apple|orange|banana".split("|", 1)[0] == "apple"'
1000000 loops, best of 3: 0.327 usec per loop
$ python -m timeit 'assert "apple|orange|banana".partition("|")[0] == "apple"'
1000000 loops, best of 3: 0.214 usec per loop
Example performance (rpartition):
$ python -m timeit 'assert "apple|orange|banana".rsplit("|")[-1] == "banana"'
1000000 loops, best of 3: 0.372 usec per loop
$ python -m timeit 'assert "apple|orange|banana".rsplit("|", 1)[-1] == "banana"'
1000000 loops, best of 3: 0.332 usec per loop
$ python -m timeit 'assert "apple|orange|banana".rpartition("|")[-1] == "banana"'
1000000 loops, best of 3: 0.219 usec per loop
