You still have the copied data which will overwrite the values
imported however to import it you need to have the path set
up correctly. Is the difflib_data.py in the same folder as difflib.py?


Your code should only need to be:

a.. import difflib
a.. from difflib_data import *
a..
a.. d = difflib.Differ()
a.. diff = d.compare(text1_lines, text2_lines)
a.. print '\n'.join(list(diff))

And provided both modules are visible to Python it should work.
Copying the data works too but I was just curious why you
needed to...
