根据多个匹配项向文本文件添加行

import fileinput

def add_lines_to_file(file_path, search_terms, new_lines):
    with fileinput.FileInput(file_path, inplace=True, backup='.bak') as file:
        for line in file:
            print(line, end='')
            if any(term in line for term in search_terms):
                for new_line in new_lines:
                    print(new_line)

# 示例用法
file_path = 'example.txt'  # 需要操作的文本文件路径
search_terms = ['apple', 'banana']  # 匹配项列表
new_lines = ['This is a new line.', 'This is another new line.']  # 需要添加的新行列表
add_lines_to_file(file_path, search_terms, new_lines)
