Python string notation
<p>I've come across some code that looks something like this:</p>

<pre><code>foo = r"""
        Hello
        How are you
        Goodbye
        """
</code></pre>

<p>Is this convention just an easy way to keep the formatting of the string that could cause problems if it was made in the normal way? I've tried searching online but the nature of the problem doesn't lend itself well to search terms.</p>
