The csv.writer.writerow() does not accept a generator as input. I find this counter-intuitive and against the spirit of similar APIs. If the generator is coerced to a list, everything works as expected. See the following test script which fails on the line "w.writerow(g)". In my opinion, this line should work identically to the line "w.writerow(list(g))".

import csv

f = open('foo.csv', 'w')
w = csv.writer(f)
g = (i for i in ['a', 'b', 'c'])
w.writerow(list(g))
g = (i for i in ['a', 'b', 'c'])
w.writerow(g)
