How to repeat individual characters in strings in Python
<p>I know that </p>

<pre><code>"123abc" * 2
</code></pre>

<p>evaluates as <code>"123abc123abc"</code>, but is there an easy way to repeat individual letters N times, e.g. convert <code>"123abc"</code> to <code>"112233aabbcc"</code> or <code>"111222333aaabbbccc"</code>?</p>
