如何编写符合PEP8的超长字符串并防止E501 [英] How to write very long string that conforms with PEP8 and prevent E501

问题描述

由于 PEP8 建议将 Python 程序的列规则保持在 80 列以下，我该如何使用长字符串来遵守该规则，即

As PEP8 suggests keeping below the 80 column rule for your python program, how can I abide to that with long strings, i.e.

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

我将如何将其扩展到以下行，即

How would I go about expanding this to the following line, i.e.

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

推荐答案

隐式串联可能是最干净的解决方案:

Implicit concatenation might be the cleanest solution:

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

编辑 经过反思，我同意 Todd 的建议使用括号而不是行继续符，因为他给出的所有原因都更好.我唯一的犹豫是将括号内的字符串与元组混淆相对容易.

Edit On reflection I agree that Todd's suggestion to use brackets rather than line continuation is better for all the reasons he gives. The only hesitation I have is that it's relatively easy to confuse bracketed strings with tuples.
