有没有一种干净的方法可以在 Python 中编写多行字符串? [英] Is there a clean way to write multi-lines strings in Python?

问题描述

这听起来像是一个初学者的问题，但我从来没有成功地用 Python 以干净的方式编写长字符串.

这是我列出的 4 种方法.在我看来，它们都不好.

def useless_func():# 错误的方式 A : string_A 显示良好，但打破了 PEP 8 建议的最大 80 个字符string_A = "Lorem ipsum dolor sat amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut Labore et dolore magna aliqua."# 错误的方式 B : string_B 将在打印时在单词 'sed' 和 'do' 之间创建不需要的空格string_B = "Lorem ipsum dolor sat amet, consectetur adipisicing elit, sed\do eiusmod tempor incididunt ut laboure et dolore magna aliqua."# WRONG WAY C : string_C 显示良好，但使我的代码难看，因为它破坏了缩进string_C = "Lorem ipsum dolor sat amet, consectetur adipisicing elit, sed\do eiusmod tempor incididunt ut laboure et dolore magna aliqua."# 错误的方式 D : string_D(三引号)与 string_B(不需要的空格)有同样的问题string_D = '''Lorem ipsum dolor sat amet, consectetur adipisicing elit, seddo eiusmod tempor incididunt ut laboure et dolore magna aliqua.'''

我错过了什么吗?

解决方案

你可以试试:

string = "sdfsdfsdfsdfsdf" \sdfsdfsdfsdfs"

结果:

<预><代码>>>>细绳'sdfsdfsdfsdfsdfsdfsdfsdfsdfs'

使用括号代替 \ 可以达到同样的效果，正如@Nigel Tufnel 在他的回答中提到的那样.

It sounds like a beginner question, but I never succeeded in writing long strings in a clean way in Python.

Here are the 4 ways I listed to do it. None of them seems ok to me.

def useless_func():
    # WRONG WAY A : string_A displays well but breaks the 80 char max PEP 8 recommandation
    string_A = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY B : string_B will create unwanted spaces between word 'sed' and 'do' when printed
    string_B = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed\
        do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY C : string_C displays well  but makes my code ugly because it breaks indentation
    string_C = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed\
do eiusmod tempor incididunt ut labore et dolore magna aliqua."

    # WRONG WAY D : string_D (triples quotes) has the same problem than string_B (unwanted spaces)
    string_D = '''Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed
        do eiusmod tempor incididunt ut labore et dolore magna aliqua.'''

Am I missing something?

解决方案

You can try:

string = "sdfsdfsdfsdfsdf" \
         "sdfsdfsdfsdfs"

And the result:

>>> string
'sdfsdfsdfsdfsdfsdfsdfsdfsdfs'

The same effect can be achieved by using paranthesis instead of \, as @Nigel Tufnel mentioned in his answer.
