在Python程序中处理每个单词可以通过以下几种方式:
sentence = "Hello, world! This is a Python program."
words = sentence.split()
print(words)
输出结果为:'Hello,', 'world!', 'This', 'is', 'a', 'Python', 'program.'
import re
sentence = "Hello, world! This is a Python program."
words = re.findall(r'\b\w+\b', sentence)
print(words)
输出结果为:'Hello', 'world', 'This', 'is', 'a', 'Python', 'program'
import nltk
sentence = "Hello, world! This is a Python program."
words = nltk.word_tokenize(sentence)
print(words)
输出结果为:'Hello', ',', 'world', '!', 'This', 'is', 'a', 'Python', 'program', '.'
以上是处理Python程序中每个单词的几种常见方法。根据具体的需求和场景选择合适的方法进行处理。
