Split string into strings by length?
<p>Is there a way to take a string that is <code>4*x</code> characters long, and cut it into 4 strings, each <code>x</code> characters long, without knowing the length of the string?</p>

<p>For example:</p>

<pre><code>&gt;&gt;&gt;x = "qwertyui"
&gt;&gt;&gt;split(x, one, two, three, four)
&gt;&gt;&gt;two
'er'
</code></pre>
