    import difflib

    file1 = file("my.txt","r")
    file2 = file("new.txt","r")

    temp1_context = file1.read()
    temp2_context = file2.read()

    file1_context = temp1_context.splitlines()
    file2_context = temp2_context.splitlines()

    diff = difflib.Differ().compare(file1_context,file2_context)

    print "\n".join(list(diff))
