这些都是很好的答案，但我找不到一个编辑器插件，可以帮助我编辑“隐式连接”的字符串，所以我写了一个包，让我更容易。

在pip(安装段落)上，如果有人想查看这个旧线程的话。以html的方式格式化多行字符串(压缩空格，一个新段落有两个换行符，不用担心行间空格)。

from paragraphs import par


class SuddenDeathError(Exception):
    def __init__(self, cause: str) -> None:
        self.cause = cause

    def __str__(self):
        return par(
            f""" Y - e - e - e - es, Lord love you! Why should she die of
            {self.cause}? She come through diphtheria right enough the year
            before. I saw her with my own eyes. Fairly blue with it, she
            was. They all thought she was dead; but my father he kept ladling
            gin down her throat till she came to so sudden that she bit the bowl
            off the spoon. 

            What call would a woman with that strength in her have to die of
            {self.cause}? What become of her new straw hat that should have
            come to me? Somebody pinched it; and what I say is, them as pinched
            it done her in."""
        )


raise SuddenDeathError("influenza")

变得……

__main__.SuddenDeathError: Y - e - e - e - es, Lord love you! Why should she die of influenza? She come through diphtheria right enough the year before. I saw her with my own eyes. Fairly blue with it, she was. They all thought she was dead; but my father he kept ladling gin down her throat till she came to so sudden that she bit the bowl off the spoon.

What call would a woman with that strength in her have to die of influenza? What become of her new straw hat that should have come to me? Somebody pinched it; and what I say is, them as pinched it done her in.

一切都很容易与(Vim)对齐“gq”

我觉得你问题中最重要的一个词是“suggest”。

编码标准是很有趣的东西。通常他们提供的指导在编写时有很好的基础(例如，大多数终端无法在一行上显示> 80个字符)，但随着时间的推移，它们在功能上变得过时了，但仍然被严格遵守。我猜您在这里需要做的是权衡“破坏”特定建议与代码的可读性和可维护性之间的相对优点。

抱歉，这并不能直接回答你的问题。

您丢失了一个空格，您可能需要一个行延续字符，即。一个\。

s = "this is my really, really, really, really, really, really" +  \
    " really long string that I'd like to shorten."

甚至:

s = "this is my really, really, really, really, really, really"  \
    " really long string that I'd like to shorten."

parns也可以代替行续符，但可能会有人认为您打算使用元组，而只是忘记了逗号。举个例子:

s = ("this is my really, really, really, really, really, really"
    " really long string that I'd like to shorten.")

对比:

s = ("this is my really, really, really, really, really, really",
    " really long string that I'd like to shorten.")

使用Python的动态类型，代码可以以任何一种方式运行，但会产生不正确的结果。

使用黑色[https://github.com/psf/black]，我像这样格式化它。

   help=f"""filters, lista de filtros para cargar las base de conocimiento.
   Pueden mandarse solo algunos filtros ya que no son obligatorios,
   por ejemplo, si no se manda sts, se cargarán todos las bases de todos los estados.""",

如果你必须插入一个长字符串文字，并希望flake8关闭，你可以使用它的关闭指令。例如，在一个测试例程中，我定义了一些假的CSV输入。我发现把它分成更多行会非常混乱，所以我决定添加一个# noqa: E501，如下所示:

这个语法适合我。注意第二个语句的缩进，它应该缩进正确。
