<p>I want to build a bot that asks someone a few simple questions and branches based on the answer. I realize parsing meaning from the human responses will be challenging, but how do you setup the program to deal with the "state" of the conversation?</p>

I wrote something a long time ago (the code to which I'm not proud of at all, and needs some mods to run on Python > 1.5) that may be a useful starting place for you: ... | <p>I would suggest looking at Bayesian probabilities.

<p>In the past we declared properties like this:</p>
<pre><code>public class MyClass
{
private int _age;
public int Age
{
get{ return _age; }
set{ _age = value; }
}
}
</code></pre>
<p>Now we can do:</p>
<pre><code>public class MyClass
{
public int Age {get; set;}
}
</code><... | <p>The aim of the new automatic properties is to reduce the amount of boilerplate code you need to write when you just have a simple property that doesn't need any special logic in the get or the set. </p>
<p>If you want to access the private member that these properties use, that's usually for a few reasons:</p>

I agree that it is slightly weird for the class to internally have to use the public entry point to access its own variables. Hence I don't use this new feature that much myself.</... | 8,672 |
