attribute assignment order in class definition
<p>Hi my problem is that: 
I want to define a class in this way:</p>

<pre><code>class List(Base):
    hp = Column(int,...)
    name = Column(str,...)
</code></pre>

<p>This class represents a list, I can define/modify/code the <code>Base</code> and the <code>Column</code> class.
There's a way to know the order in which I defined the attributes hp/names?
For example I want to define a method that can do this:</p>

<pre><code>l = List()
l.show()
[(hp,16),(name,roger)] # in this order
</code></pre>
