of course it does:
>>> lines = ["line\tone", "line\ttwo"]
>>> [s.split("\t") for s in lines]
[['line', 'one'], ['line', 'two']]
>>> map(str.split, lines)
[['line', 'one'], ['line', 'two']]
the problem is that he's using a Python-level profiler to benchmark things
written
in C.
(you cannot really use "profile" to *benchmark* things written in Python
either; the
profiler tells you where a given program spends the time, not how fast it is in
com-
parision with other programs)
