Reading a CSV file using Python

Question

please tell me what's the problem in this code it's giving an error

import csv
with open('some.csv', 'rb') as f:
    reader = csv.reader(f)
    for row in reader:
        print row

Answer 1

Which version of Python are you using?

The with statement is new in 2.6 - if you're using 2.5 you need from __future__ import with_statement . If you use a Python older than 2.5 then there's no with statement, so just write:

import csv
f = open('some.csv', 'rb')
reader = csv.reader(f)
for row in reader:
    print row
f.close()

It's really better to update to a modern version of Python, though. Python 2.5 was released almost 5 years ago, and the current version in the 2.x line is 2.7

Answer 2

from __future__ import with_statement

如果不工作，重写它不使用with在首位。
