Adding variably named fields to Python classes
<p>I have a python class, and I need to add an arbitrary number of arbitrarily long lists to it. The names of the lists I need to add are also arbitrary. For example, in PHP, I would do this:</p>

<pre><code>class MyClass {

}

$c = new MyClass();
$n = "hello"
$c.$n = array(1, 2, 3);
</code></pre>

<p>How do I do this in Python?</p>

<p>I'm also wondering if this is a reasonable thing to do. The alternative would be to create a dict of lists in the class, but since the number and size of the lists is arbitrary, I was worried there might be a performance hit from this.</p>

<p>If you are wondering what I'm trying to accomplish, I'm writing a super-lightweight script interpreter. The interpreter walks through a human-written list and creates some kind of byte-code. The byte-code of each function will be stored as a list named after the function in an "app" class. I'm curious to hear any other suggestions on how to do this as well.</p>
