&gt; Michael,
&gt; 
&gt;     Actually python does have a mechanism, albeit a big odd, for
making
&gt; data private but it is not standard python practice to use
getter/setter
&gt; methods. Indeed, its generally poor practice in most languages but I
see
&gt; a lot of poorly written C++ &amp; Java strewn with it. There is the
&gt; occasional need for these accessors in some languages but python has
&gt; gone even further and completely eliminated their need by explicit
&gt; support for properties. Properties allows your class users to use
syntax
&gt; just like they were accessing the data members directly but actually
&gt; routes the access through methods in the class that validate,
&gt; manipulate, or generally enforce the interface to that data. Indeed,
&gt; through this method one can define read-only (and write-only!)
&gt; properties giving your data further protection. This provides for
better
&gt; enforcement of encapsulation whereas in most cases where you see
&gt; getter/setter methods, you've actually identified a violation of
&gt; encapsulation and poor design.

&lt;google_search ... read .. &gt; 

Wow, that's pretty cool.  Is there a way to do it where you don't have
to write the getter/setter?  So, if I'd like to have a variable exposed
to read and write I don't need to do anything because by default
everything is available outside the class.  But if I want a read only
member, I need to setup a reader methods and declare it.  What I'd
really like is declare a member read only, but not have to write
accessor methods unless they are needed.  I didn't see that mentioned in
any of the docs.  Did I miss it?

Thanks,

Michael
