从多行字符串中提取单词

import re

def extract_words_from_multiline_string(multiline_string):
    # 将多行字符串转换为单行字符串
    single_line_string = multiline_string.replace('\n', ' ')

    # 使用正则表达式匹配并提取单词
    words = re.findall(r'\b\w+\b', single_line_string)

    return words

# 示例用法
multiline_string = '''
Hello, how are you?
I'm doing great, thank you!
'''
words = extract_words_from_multiline_string(multiline_string)
print(words)

['Hello', 'how', 'are', 'you', 'I', 'm', 'doing', 'great', 'thank', 'you']
