Apparently not, although I remember that I did some tests in which csv
was faster. So, I'd appreciate some advice when to use split() and
when to use csv!
sage: L=[str(i) for i in range(10000)]
sage: s=','.join(L)
sage: import csv
sage: s.split(',')==list(csv.reader([s]))[0]
True
sage: timeit("s.split(',')")
625 loops, best of 3: 438 µs per loop
sage: timeit("list(csv.reader([s]))[0]")
625 loops, best of 3: 788 µs per loop
Cheers,
Simon
