在Python中解析直到某个内容的文件

def parse_file(file_path, target_content):
    with open(file_path, 'r') as file:
        content = file.read()
        index = content.find(target_content)
        if index != -1:
            parsed_content = content[:index + len(target_content)]
            return parsed_content
        else:
            return "Target content not found in the file."

# 示例用法
file_path = 'example.txt'
target_content = '某个内容'
parsed_content = parse_file(file_path, target_content)
print(parsed_content)
