如何逐行检查文本文件中的单词，并在找到时打印整行

import re

def search_word(file_path, target_word):
    with open(file_path, 'r') as file:
        line_number = 0
        for line in file:
            line_number += 1
            if re.search(r'\b{}\b'.format(target_word), line):
                print("Line {}: {}".format(line_number, line.strip()))

# 示例使用
file_path = 'example.txt'  # 文本文件的路径
target_word = 'example'  # 目标单词

search_word(file_path, target_word)
