Making list of first line and everything else from a string
<p>There is a string:</p>

<pre><code>str = "first line\n xxxxxxxxxxxxx\n zzzzzzzzzzzzzzz"
</code></pre>

<p>I need to get a list with two elements: first line and everything else:</p>

<pre><code>list = ['first line\n', ' xxxxxxxxxxxxx\n zzzzzzzzzzzzzzz']
</code></pre>

<p>How can I do it?</p>
