处理 python 类型注释时的 79 个字符限制
Dealing with the 79 character limit when writing python type annotations
在编写脚本时,我最终得到了如下所示的函数签名
def do_multiprocess_action(some_argument: str, communication_pipe: typing.Optional[multiprocessing.connection.Connection]) -> subprocess.Popen:
为了符合 PEP8,我将定义拆分如下
def do_multiprocess_action(some_argument: str,
communication_pipe: typing.Optional[multiprocessing.connection.Connection]
) -> subprocess.Popen:
但是使用类型注释,这一行太长了。处理此问题的惯用方法是什么?
您可以先定义注释,然后再编写函数:
MultiprocessingConnection = typing.Optional[
multiprocessing.connection.Connection]
def do_multiprocess_action(some_argument: str,
communication_pipe: MultiprocessingConnection) -> subprocess.Popen:
