Short sections of code are not where classes shine. <br><br>Classes become much more valuable when you start to get a lot of hairy details you need to pass around. For your code, for instance, you could pass in the whole registry key you want, and have out pop a RegKey object.
<br><br>This would be say, usable in a system where you needed to do several operations on this object. If you were accessing multiple registry keys for instance, it would probably be nice to make a RegKey class that could be created with a handy method. If you were only accessing one key one time, a simple routine will serve you well.
<br><br>Realms where classes are almost always used<br>Simulations, GUI elements, business systems of any size, many parsers, especially XML and HTML parsers.<br><br>Realms where they're used much less:<br>Basic text processing, system administration tasks, simple database systems, and number crunching apps.

I am still trying to understand when to use a class and when not to. All<br>of the coding that I have done in the past (Python, Perl) has been<br>procedural / functional. I would really like to do more OOP but I am not<br>
really sure when I need it.<br><br>I have the following code. Is there any way that it would benefit from<br>using a class?<br><br><code><br><br>#!/usr/bin/env python<br><br>import string<br>import _winreg<br>import sys
<br><br>compName = sys.argv[1]<br><br>x = _winreg.ConnectRegistry(compName,_winreg.HKEY_LOCAL_MACHINE)<br>y = _winreg.OpenKey(x,<br>r"SOFTWARE\Intel\LANDesk\VirusProtect6\CurrentVersion")<br>avParent = _winreg.QueryValueEx(y,"Parent")[0]
<br><br>_winreg.CloseKey(y)<br><br>print "Computer: %s \tAV Parent: %s" % (compName,avParent)<br><br></code><br><br><br>--<br><br>Thanks<br>Eric Lake<br><br>-----BEGIN PGP SIGNATURE-----<br>Version: GnuPG
