python difflib comparing files

Question

I am trying to use difflib to produce diff for two text files containing tweets. Here is the code:

#!/usr/bin/env python

# difflib_test

import difflib

fil         


        

Answer 1

Just parse output of diff like this (change '- ' to '+ ' if needed):

#!/usr/bin/env python

# difflib_test

import difflib

file1 = open('/home/saad/Code/test/new_tweets', 'r')
file2 = open('/home/saad/PTITVProgs', 'r')

diff = difflib.ndiff(file1.readlines(), file2.readlines())
delta = ''.join(x[2:] for x in diff if x.startswith('- '))
print delta
