Question

I have some very simple piece of code:

import csv
out = csv.writer(open('test.csv', 'wb'), delimiter=",")
out.writerow([u"value1", u"value2", u"value3"])

It sometimes works, but most of the time it doesn’t! I remember I used writerow previously and it was working just fine, what am I missing here?

To make the problem clearer: the csv file remains empty although the above code is executed without any errors

Answer 1

I modified the code to look as follows:

import csv
f = open('test.csv', 'wb')
out = csv.writer(f, delimiter=",")
out.writerow([u"value1", u"value2", u"value3"])
f.close()

So all I’ve done is that I separated the open('test.csv', 'wb') and assigned it to f, so that I can use f.close() at the end. It works perfectly this way.
