ImportError :No module named difflib_data

I am working with python 3.4 in windows 7.Trying to compare two text files and i want to report the differences in them using difflib. Following is the code m using:

import difflib
from difflib_data import *

with open("s1.txt") as f, open("s2.txt") as g:
    flines = f.readlines()
    glines = g.readlines()

d = difflib.Differ()
diff = d.compare(flines, glines)
print("\n".join(diff))

Traceback: from difflib_data import * ImportError: No module named 'difflib_data'

How to remove this error....thanks

Solution

  • From the following post, it seems it is the example data provided with the PyMOTW tutorial.

    I assume the author wants you to copy and paste the source of test data into a new file named difflib_data.py in your working dir.

    Copy the following lines into difflib_data.py

    text1 = """Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integereu lacus accumsan arcu fermentum euismod. Donec pulvinar porttitortellus. Aliquam venenatis. Donec facilisis pharetra tortor. In necmauris eget magna consequat convallis. Nam sed sem vitae odiopellentesque interdum. Sed consequat viverra nisl. Suspendisse arcumetus, blandit quis, rhoncus ac, pharetra eget, velit. Maurisurna. Morbi nonummy molestie orci. Praesent nisi elit, fringilla ac,suscipit non, tristique vel, mauris.

text1_lines = text1.splitlines()

text2 = """Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integereu lacus accumsan arcu fermentum euismod. Donec pulvinar porttitortellus. Aliquam venenatis.

text2_lines = text2.splitlines()
