Answer 1

import csv 

data=[('name', 'sex', 'date'), ('x1', 'f', '1948/05/28'), ('x2', 'm', '1952/03/27'),\
        ('x3', 'f', '1994/12/09'), ('x4', 'f', '1969/08/02')]
with open("g:\\test","w")  as f:
    writer=csv.writer(f, delimiter=", ", lineterminator="\r\n") 
    writer.writerows(data)

Spot "s" at the end of writerows . Also, see delimiter and lineterminator arguments.

To be frank, I can't get what your problem is - values above are default, so your format should be OK...

Answer 2

writer.writerow writes a single line. Multiple lines are written with writer.writerows. This is given in the docs .
