Python中使用pyyaml对yaml文件进行读写删操作

安装库

pip install pyyaml

读取yaml/yam格式的文件

def get_yaml(filepath) -> list:
    """
    :param filepath: 文件路径
    :return: 传入数据的列表
    """
    data = open(filepath, 'r', encoding='utf-8')
    res = yaml.load(data, Loader=yaml.FullLoader)
    data.close()
    return res

写入数据,通过type参数来控制覆盖或追加

def write_yaml(filepath, data, type) -> None:
    """
    :param filepath: 文件路径
    :param list: 参数列表
    :param type: W:覆盖编辑 A:追加编辑
    """
    cur_path = os.path.dirname(os.path.realpath(__file__))
    yaml_path = os.path.join(cur_path, filepath)
    with open(yaml_path, type, encoding="utf-8") as f:
        yaml.dump(data, stream=f, allow_unicode=True, )

清除文件内容

def clear_yaml_data(filepath) -> None:
    """
    :param filepath: 文件路径
    """
    fo = open(filepath, 'w', encoding='utf-8')
    fo.truncate()
