reading csv file without for

Question

I need to read a CSV file in python.

Since for last row I receive a \'NULL byte\' error I would like to avoid using for keyword but the while.

Do you know ho

Answer 1

I don't have an answer, but I can confirm the problem, and that most answers posted don't work. You cannot catch this exception. You cannot test for if line. Maybe you could check for the NULL byte directly, but I'm not swift enough to do that... If it is always on the last line, you could of course skip that.

import csv
FH = open('data.csv','wb')
line1 = [97,44,98,44,99,10]
line2 = [100,44,101,44,102,10]
for n in line1 + line2:
    FH.write(chr(n))
FH.write(chr(0))
FH.close()
FH = open('data.csv')
reader = csv.reader(FH)
for line in reader:
    if '\0' in line:  continue
    if not line:  continue
    print line

$ python script.py 
['a', 'b', 'c']
['d', 'e', 'f']
Traceback (most recent call last):
  File "script.py", line 11, in 
    for line in reader:
_csv.Error: line contains NULL byte
