Properties in Python
<p>whats the reason to use the variable the self._age?  A similar name that doesn't link to the already used self.age?</p>

<pre><code>class newprops(object):
    def getage(self):
        return 40
    def setage(self, value):
        self._age = value
    age = property(getage, setage, None, None)
</code></pre>
