<FONT><h3>Methods Handling</h3>
<p>Whenever you have to write methods in your classes, always keep in mind that the namespace searching order for attributes and methods is instance, class, and base classes; and don't forget that <tT CLAss="monofont">self</tt> is always the first or only argument to be used in method headers.</P>
<H4>Accessing Unbounded Methods</H4>
<P>The next example shows what you should do in order to unbind a class method and use it outside the class definition.</p>
<pre>
1: obj = classname()
2: umethod = classname.methodname()
3: umethod(obj, args)
</PRE>
<P>Line 1: Creates a class instance object.</p>
<p>Line 2: Creates an object that references the class method. The method is still unattached to the object at this stage.</p>
<p>Line 3: Executes the class method by transporting the instance reference (<tt class="monofont">obj</tt>) and the list of arguments (<tt class="monofont">args</Tt>).</p>
<P>Note that the first argument to an unbound method must be an instance of the correct class, or an exception will be thrown.<a naMe="idx1073743383"></a><a nAme="idx1073743384"></a><A NAMe="idx1073743385"></a><a nAME="idx1073743386"></A><a namE="idx1073743387"></A><A Name="idx1073743388"></a><A NAMe="idx1073743389"></a></p>
<h4>Handling Global Class Variables</h4>
<p>The next example defines a function that prints a class variable. Every time a new instance is created, <tt class="monofont">Globalcount</tt> increases.</p>
