我正在編寫一個腳本，如果兩行之間的三個連續單詞匹配，該腳本將認為兩行是重復的。假設我當前的數據集是：1 A Course of Pure Mathematics by G. H. Hardy2 Agile Software Development, Principles, Patterns, and Practices by Robert C. Martin3 Advanced Programming in the UNIX Environment, 3rd Edition4 Advanced Selling Strategies: Brian Tracy5 Advanced Programming in the UNIX(R) Environment6 Alex's Adventures in Numberland: Dispatches from the Wonderful World of Mathematics by Alex Bellos, Andy Riley7 Advertising Secrets of the Written Word: The Ultimate Resource on How to Write Powerful Advertising8 Agile Software Development, Principles, Patterns, and Practices9 A Course of Pure Mathematics (Cambridge Mathematical Library) 10th Edition by G. H. Hardy 10 Alex’s Adventures in Numberland11 Advertising Secrets of the Written Word12 Alex's Adventures in Numberland Paperback by Alex Bellos這里，1 和 9 是重復的，因為course pure mathematics匹配。2 和 8 是重復的，因為advanced programming unix匹配。3 和 5 是重復的，因為advanced programming unix匹配。等等 ...

OP 這里，解決方案似乎是：
import re
from nltk.util import ngrams
OriginalBooksList = list()
booksAfterRemovingStopWords = list()
booksWithNGrams = list()
stopWords = ['I', 'a', 'about', 'an', 'are', 'as', 'at', 'be', 'by', 'com', 'for', 'from', 'how', 'in', 'is', 'it', 'of', 'on', 'or', 'that', 'the', 'this', 'to', 'was', 'the',
'and', 'A', 'About', 'An', 'Are', 'As', 'At', 'Be', 'By', 'Com', 'For', 'From', 'How', 'In', 'Is', 'It', 'Of', 'On', 'Or', 'That', 'The', 'This', 'To', 'Was', 'The', 'And']
with open('UnifiedBookList.txt') as fin:
for line_no, line in enumerate(fin):
OriginalBooksList.append(line)
line = re.sub(r'[^\w\s]', ' ', line) # replace punctuation with space
line = re.sub(' +', ' ', line) # replace multiple space with one
line = line.lower() # to lower case
if line.strip() and len(line.split()) > 2: # line can not be empty and line must have more than 2 words
booksAfterRemovingStopWords.append(' '.join([i for i in line.split(
) if i not in stopWords])) # Remove Stop Words And Make Sentence
for line_no, line in enumerate(booksAfterRemovingStopWords):
tokens = line.split(" ")
output = list(ngrams(tokens, 3))
temp = list()
temp.append(OriginalBooksList[line_no]) # Adding original line
for x in output: # Adding n-grams
temp.append(' '.join(x))
booksWithNGrams.append(temp)
while booksWithNGrams:
first_element = booksWithNGrams.pop(0)
x = 0
for mylist in booksWithNGrams:
if set(first_element) & set(mylist):
if x == 0:
print(first_element[0])
x = 1
# print(set(first_element) & set(mylist))
print(mylist[0])
booksWithNGrams.remove(mylist)
x = 0
