正如PEP8所建议的那样，在python程序中保持低于80列的规则，对于长字符串，我怎么能遵守这个规则呢?
s = "this is my really, really, really, really, really, really, really long string that I'd like to shorten."
我该如何把它扩展到下面一行呢?
s = "this is my really, really, really, really, really, really" +
"really long string that I'd like to shorten."
当前回答
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。
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。

por ejemplo, si no se manda sts, se cargarán todos las bases de todos los estados.""",
