Python风格 - 字符串的连续性？ [英] Python style - line continuation with strings?

问题描述

在尝试服从python风格规则，我已经设置我的编辑器最多79 cols。

In trying to obey the python style rules, I've set my editors to a max of 79 cols.

在PEP，它建议使用python的隐含的延续括号，括号和大括号。

In the PEP, it recommends using python's implied continuation within brackets, parentheses and braces. However, when dealing with strings when I hit the col limit, it gets a little weird.

例如，尝试使用多行

mystr = """Why, hello there
wonderful stackoverflow people!"""

将返回

"Why, hello there\nwonderful stackoverflow people!"

这样工作：

mystr = "Why, hello there \
wonderful stackoverflow people!"

由于它返回：

"Why, hello there wonderful stackoverflow people!"

但是，当语句缩进几个块时，这看起来很奇怪：

But, when the statement is indented a few blocks in, this looks weird:

do stuff:
    and more stuff:
        and even some more stuff:
            mystr = "Why, hello there \
wonderful stackoverflow people!"

如果您尝试缩进第二行：

If you try and indent the second line:

do stuff:
    and more stuff:
        and even some more stuff:
            mystr = "Why, hello there \
            wonderful stackoverflow people!"

您的字符串最后为：

"Why, hello there                wonderful stackoverflow people!"

我发现要解决这个问题的唯一方法是：

The only way I've found to get around this is:

do stuff:
    and more stuff:
        and even some more stuff:
            mystr = "Why, hello there" \
            "wonderful stackoverflow people!"

我喜欢更好，但也有些不安的眼睛，因为它看起来像字符串只是坐在无处的中间。这将产生正确的：

Which I like better, but is also somewhat uneasy on the eyes, as it looks like there is a string just sitting in the middle of nowhere. This will produce the proper:

"Why, hello there wonderful stackoverflow people!"

所以，我的问题是 - 一些人的建议如何做到这一点，

So, my question is - what are some people's recommendations on how to do this and is there something I'm missing in the style guide that does show how I should be doing this?

感谢。

推荐答案

由于相邻字符串文字会自动合并为单个字符串，你可以使用PEP 8建议的括号内的隐式行继续：

Since adjacent string literals are automatically joint into a single string, you can just use the implied line continuation inside parentheses as recommended by PEP 8:

print("Why, hello there wonderful "
      "stackoverflow people!")
