You lost a space, and you probably need a line continuation character, ie. a <code>\</code>.

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

or even:

<pre><code>s = "this is my really, really, really, really, really, really" \
 " really long string that I'd like to shorten."
</code></pre>

Parens would also work instead of the line continuation, but you risk someone thinking you intended to have a tuple and had just forgotten a comma. Take for instance:

<pre><code>s = ("this is my really, really, really, really, really, really"
 " really long string that I'd like to shorten.")
</code></pre>

versus:

<pre><code>s = ("this is my really, really, really, really, really, really",
 " really long string that I'd like to shorten.")
</code></pre>

With Python's dynamic typing, the code may run either way, but produce incorrect results with the one you didn't intend.

I think the most important word in your question was "suggests". 

Coding standards are funny things. Often the guidance they provide has a really good basis when it was written (e.g. most terminals being unable to show > 80 characters on a line), but over time they become functionally obsolete, but still rigidly adhered to. I guess what you need to do here is weigh up the relative merits of "breaking" that particular suggestion against the readability and mainatinability of your code.

Sorry this doesn't directly answer your question.

Since neighboring string constants are automatically concatenated, you can code it like this:
<pre><code>s = (&quot;this is my really, really, really, really, really, really, &quot; 
 &quot;really long string that I'd like to shorten.&quot;)
</code></pre>
Note no plus sign, and I added the extra comma and space that follows the formatting of your example.
Personally I don't like the backslashes, and I recall reading somewhere that its use is actually deprecated in favor of this form which is more explicit. Remember &quot;Explicit is better than implicit.&quot;
I consider the backslash to be less clear and less useful because this is actually escaping the newline character. It's not possible to put a line end comment after it if one should be necessary. It is possible to do this with concatenated string constants:
<pre><code>s = (&quot;this is my really, really, really, really, really, really, &quot; # comments ok
 &quot;really long string that I'd like to shorten.&quot;)
</code></pre>
<hr />
I used a Google search of &quot;python line length&quot; which returns the PEP8 link as the first result, but also links to another good StackOverflow post on this topic: &quot;<a href="https://stackoverflow.com/questions/88942/why-should-python-pep-8-specify-a-maximum-line-length-of-79-characters">Why should Python PEP-8 specify a maximum line length of 79 characters?</a>&quot;

I've used textwrap.dedent in the past. It's a little cumbersome so I prefer line continuations now but if you really want the block indent, I think this is great. 

Example Code (where the trim is to get rid of the first '\n' with a slice):

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

Explanation: 

dedent calculates the indentation based on the white space in the first line of text before a new line. If you wanted to tweak it, you could easily reimplement it using the <code>re</code> module.

This method has limitations in that very long lines may still be longer than you want in which case other methods that concatenate strings is more suitable.

These are all great answers, but I couldn't find an editor plugin that would help me with editing "implicitly concatenated" strings, so I wrote a package to make it easier on me.

On pip (install paragraphs) if whoever's wandering this old thread would like to check it out. Formats multi-line strings the way html does (compress whitespace, two newlines for a new paragraph, no worries about spaces between lines).

<pre><code>from paragraphs import par
