[Python] compares different places in strings

The question is from the Challenge 'didactic text' [Crypto] of hacker.org.

Analyze the given articles to find out the hidden words.

 

Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all the men are created equal.Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this solution.But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, is far above our poor power to add or detract. The world will little note, nor long remember what we say here today, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the brave unfinished work which they who fought here have thus far so nobly advanced. It is rather for us solvers to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.

 

The difflib module of python is compared with the original text to identify the differences.

---

 

from difflib import *file_1 = open("a.txt")file_2 = open("b.txt")s_1 = file_1.read()s_2 = file_2.read()s = HtmlDiff.make_file(HtmlDiff(),s_1,s_2)out = open(r"res.html","w")out.write(s)

Read two articles into the string and use HtmlDiff in the difffib module to output the comparison result in html format.

At last, we found that the given Article has more words than the original one.
