If your lines are variable-length, then look at itertools recipes.
from itertools import izip_longest
def grouper(n, iterable, fillvalue=None):
"grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
args = [iter(iterable)] * n
return izip_longest(fillvalue=fillvalue, *args)
with open("/file","r") as f:
for lines in grouper(65535,f,""):
data_to_write = '\n'.join(lines).rstrip("\n")
...
<write data where you need it here>
