读取yaml文件

def read_yaml(yml_file, mode='r', encoding='utf-8'): """ yaml中内容读取并转化为Python对象 :param yml_file: :param mode: :param encoding: :return: """ # safe_load_all() 打开多个文档 with open(yml_file, mode=mode, encoding=encoding) as y_file: # .load 是非推荐的 不安全的编码方式 # content = yaml.load(y_file.read(), yaml.FullLoader) # .safe_load 安全编码方式 # If you don't trust the input stream, you should use: return yaml.safe_load(y_file)

写入yaml文件

def write_yaml(yaml_file, data, mode='w', encoding='utf-8', is_flush=True): """ Python对象转换为 yaml :param yaml_file: :param data: :param mode: :param encoding: :param is_flush: :return: """ with open(yaml_file, mode=mode, encoding=encoding) as y_file: # yaml.dump(data, stream=y_file) # allow_unicode 解决写入乱码的问题 yaml.safe_dump(data, stream=y_file, allow_unicode=True) if is_flush: y_file.flush()
