You should post some code anyway, it would be easier to give useful advice (it
would also demonstrate that you put some effort on it).
Anyway, here is an option. Text-file objects are line-iterable, so you could
use
itertools (perhaps a bit difficult module for a newbie...):
from itertools import islice, takewhile, repeat
def take(it, n):
return list(islice(it, n))
def readnlines(fd, n):
return takewhile(bool, (take(fd, n) for _ in repeat(None)))
def splitfile(path, prefix, nlines, suffix_digits):
sformat = "%%0%dd" % suffix_digits
for index, lines in enumerate(readnlines(file(path), nlines)):
open("%s_%s"%(prefix, sformat % index), "w").writelines(lines)
splitfile("/etc/services", "out", 5, 4)
