Where do you get the data from in the "real world"? If it's a file you might
get the best overall performance if you skip the readlines() call:
sp0(f)
Anyway, here's another variant you can try:
from itertools import izip, starmap, repeat
def splitlines(lines):
return list(starmap(str.split, izip(lines, repeat("\t"))))
