How to data print data to CSV using Python

Question

I created a python program to provide a diff file. Wanted to know what the best way to send the results of the diff into a .csv would be

Here's my code,

import difflib

file1 = "swiss1.csv"
file2 = "swiss2.csv"

diff = difflib.ndiff(open(file1).readlines(),open(file2).readlines())

for line in diff:
    if line[0] in ["+", "-"]:
        print line

Rather than print to the terminal I would like to print it to a CSV file. Thoughts?

Answer 1

import difflib
import csv
file1 = "swiss1.csv"
file2 = "swiss2.csv"

diff = difflib.ndiff(open(file1).readlines(),open(file2).readlines())
f = open('changes.csv','w')
for line in diff:
    if line[0] in ["+", "-"]:
        f.write(line)
f.close()
