我必须找到两个段落之间的共同词并打印出来

Answer 1

如果您不需要在语言处理方面做一些特殊的事情，则不需要 NLTK：

paragraph1 = paragraph1.lower().split()
paragraph2 = paragraph2.lower().split()

intersection = set(words1) & set(words2)

Answer 2

您可以使用set.intersection。

p1 = '''
Electronic commerce, commonly written as E-Commerce, is the trading or  
facilitation of trading in goods or services using computer networks, such 
as the Internet or online social networks. Electronic commerce draws on 
technologies such as mobile commerce, electronic funds transfer, supply 
chain management, Internet marketing, online transaction processing, 
electronic data interchange (EDI), inventory management systems, and 
automated data collection systems.
'''.split()

p2 = '''
Modern electronic commerce typically uses the World Wide Web for at least 
one part of the transaction's life cycle although it may also use other 
technologies such as e-mail. The benefits of e-commerce include it’s the 
speed of access, a wider selection of goods and services, accessibility, and 
international reach.
'''.split()

print(set(p1).intersection(p2))
{'and', 'the', 'technologies', 'of', 'electronic', 'such', 'commerce', 'as', 'goods'}
