在Python中查找与多行字符串匹配的文件名

import re
import os

def find_matching_filenames(directory, pattern):
    matching_filenames = []
    regex = re.compile(pattern, re.MULTILINE)
    
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            
            with open(file_path, 'r') as f:
                content = f.read()
                
                if regex.search(content):
                    matching_filenames.append(file_path)
    
    return matching_filenames

directory = '/path/to/directory'
pattern = r'multi-line string pattern'

matching_filenames = find_matching_filenames(directory, pattern)
for filename in matching_filenames:
    print(filename)
