python: in ""?
<p>I stumbled upon <a href="https://raw.github.com/jackjack-jj/pywallet/278c6e08d29958be78c0586d9457d602b9296274/pywallet.py">this</a> apparently horrific piece of code:</p>

<pre><code>def determine_db_name():
    if wallet_name in "":
        return "wallet.dat"
    else:
        return wallet_name
</code></pre>

<p>What is supposed <code>if xx in "":</code> to mean? Doesn't it always evaluates to <code>False</code>?</p>
