-

i writing simple script python3.6 , using csv module create csv file. code attached below, , carbon copy of multiple examples have found online, when run code, error message typeerror: bytes-like object required, not 'str'.

import csv file_name = test.csv open(file_name, 'wb') csvfile:    filewriter = csv.writer(csvfile,delimiter=',')    filewriter = writerow(['paul','mary'])
