在python中打开.csv文件时语法无效

Question

The error message:

File "./reading_and_creating_outage_report.py", line 6
with open('major_outages_csv.csv',mode='w') as csv_file:
         ^
SyntaxError: invalid syntax

I'm stumped. Every example I've seen on Stack Overflow and elsewhere uses this syntax to open a csv file residing in the same directroy as the script. I have found other methods, but I don't like not knowing what is wrong with the way I'm writing this considering it seems to be the same all other samples.

referenced material:

https://docs.python.org/2/library/csv.html

script in question:

import csv
with open('major_outages_csv.csv',mode='w') as csv_file:
    csv_reader  = csv.reader(csv_file,delimiter=',')
    line_count = 0
    for row in csv_reader:
            if line_count == 0:
                    print('column headers are {", ".join(row)}')
                    line_count += 1
            else:
                    print('\t{row[0]} is the number of customers out and {row[1]} is the feeder.')
                    line_count += 1
    print ('processed {line_count} lines.')

UPDATE: The issue was the version of python. As mentioned in many other posts on StackExchange, python versions older than 2.5 do not support with statements.

If one wishes to read a .csv file using a version of python older than 2.5, the below script works.

import csv
csv_reader = csv.reader(open("file_name.csv","rb"),delimiter=',')
for fields in csv_reader:
     print fields
