AttributeError: '_csv.reader' object has no attribute 'next()'

[venkat01]

I am at lesson 3.3 and rdd_csv_corrrect = rdd_no_header.map(lambda line: csv.reader([line]).next()) is giving an error in .next(). i am using python 3 here.

The error is AttributeError: '_csv.reader' object has no attribute 'next()'

I think this is more of an python2 v/s python3 issue, but need clarification as to how to resolve as this is becoming a show stopper :)

The actual error is '_csv.reader' object has no attribute 'next'

I tried googling and it said to use next() and thta is also working

Hi,
For Python 3.x: Use next(reader) instead of reader.next()

#!/usr/bin/env python

import csv

csvr = csv.reader(open('fer2013.csv'))
header = csvr.next(reader)
rows = [row for row in csvr]

trn = [row[:-1] for row in rows if row[-1] == 'Training']
csv.writer(open('test.csv', 'w+')).writerows([header[:-1]] + trn)
print (trn)

tst = [row[:-1] for row in rows if row[-1] == 'PublicTest']
csv.writer(open('test.csv', 'w+')).writerows([header[:-1]] + tst)
print(tst)

tst2 = [row[:-1] for row in rows if row[-1] == 'PrivateTest']
csv.writer(open('testprivate.csv', 'w+')).writerows([header[:-1]] + tst2)
print (tst2)

And this my code
