<p>In the begining there was Python, and Python had modules, and Python
was good. But after a time Guido looked on Python and saw that Python
needed organizational assistance, and so Guido took code from Python's
<a class="reference" href="MigrationGuide.html">2.5 Migration Guide</a> to see notes about other big differences in
this release.</p>

<p>The second reason is to remove what some perceive to be a "wart." For
example, the following code is rather ugly in that the "wx" prefix on
the same thing (implement a new wx namespace and drop the "wx" prefix)
and we want wxPython to lead the way.</p>

<p>As mentioned in the Introduction, wxPython 2.4.1 introduced a way of
getting to this new syntax as quickly as possible. It would import
the old names (like "wxFrame") from the old package and then create new
complicated, but it is mostly automated and so it doesn't cause
problems in most cases.</p>

<p>No. Your existing code will continue to work and be supported for
some time. It will be up to you to decide when to switch to the new
syntax. But all new documentation and code examples will use the new
are using other things that have changed in the API. See the
<a class="reference" href="MigrationGuide.html">Migration Guide</a> for more details.</p>

<p>There's more to the old wxPython than just the wxPython.wx module.
And we've got those extra modules covered as well. Each of those
modules (as well as the lib subpackage) has been moved to the new wx
package and reverse-renamers have been placed in the wxPython package
as needed.</p>

<p>The wx package is automatically created when you install wxPython
version 2.4.1 or higher. So all you have to do is:</p>
<pre class="literal-block">
import wx

<p>Obviously, you need to change your import statements from:</p>
