如何在txt中构建一个返回匹配元素的函数。文件和字典

def find_matching_elements(file_path, target_element):
    matching_elements = []
    
    with open(file_path, 'r') as file:
        content = file.read()
        # 解析文件内容，根据具体情况进行处理
        
        # 匹配逻辑示例：假设文件内容是以逗号分隔的字符串
        elements = content.split(',')
        for element in elements:
            if element == target_element:
                matching_elements.append(element)
    
    return matching_elements

file_path = 'example.txt'
target_element = 'apple'
result = find_matching_elements(file_path, target_element)
print(result)
