Does Python csv writer always use DOS end-of-line characters?

I realize that the csv library in Python always generates DOS end-of-line characters. Even if I use the

'wb'
mode, even if I use Linux.

import csv

f = open('output.txt', 'wb');
writer = csv.writer(f)
writer.writerow([2,3,4]);
f.close()


The above code always uses
'\r\n'
as the end of line separator. How can I make it use use
'\n'
only?

Answer

You can give your writer instance a custom lineterminator argument in the constructor:

writer = csv.writer(f, lineterminator="\n")
