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)。

            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.

__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”

反斜杠:

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

或者用括号括起来:

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

使用\你可以将语句扩展到多行:

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

应该工作。

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。

我以前用过textwrap.dedent。这有点麻烦，所以我现在更喜欢行延续，但如果你真的想要块缩进，我认为这很好。

示例代码(其中trim是去掉带有切片的第一个'\n'):

import textwrap as tw
x = """\
       This is a yet another test.
       This is only a test"""
print(tw.dedent(x))

解释:

Dedent根据新行前第一行文本中的空白计算缩进。如果你想调整它，你可以使用re模块轻松地重新实现它。

这种方法有局限性，很长的行可能仍然比你想要的长，在这种情况下，其他方法连接字符串更适合。
