<p>Erlang has a concept called "atoms" -- they are similar to string constants or enumerations. Consider using a string constant as the value of your enum -- the same as the name of the enum.</p>

<p>I'm using base class constructor as factory and changing class in this constructor/factory to select appropriate class -- is this approach is good python practice or there are more elegant ways? </p> <p>I've tried to read help about metaclasses but without big success.</p> <p>Here example of what I'm doing.</p> <...

<p>I would stick with the factory function approach. It's very standard python and easy to read and understand. You could make it more generic to handle more options in several ways such as by passing in the discriminator function and a map of results to classes. </p> <p>If the first example works it's more by luck...

<p>I usually have a seperate factory class to do this. This way you don't have to use meta classes or assignments to <code>self.__class__</code></p> <p>I also try to avoid to put the knowledge about which classes are available for creation into the factory. Rather, I have all the available classes register themselves ...

<p>You shouldn't need metaclasses for this. Take a look at the <a href="http://docs.python.org/reference/datamodel.html#object.__new__"><code>__new__</code></a> method. This will allow you to take control of the creation of the object, rather than just the initialisation, and so return an object of your choosing.</p>...
