First, you don't need re for that, and second, why write a zero-length ''?
It might even confuse some file system. You don't need readlines either. Try
(untested)
# open f and w as before [1]
for line in f:
if line.strip(): w.write(line) # write only non-blank lines
[1] BTW, I didn't see the 't' mode in
http://docs.python.org/lib/built-in-funcs.html
description of open/file, but I have a nagging doubt about saying it's not
valid.
Where did you see it?
