isinstance() and issubclass() behavior differently
<pre><code>&gt;&gt;&gt; class Hello:
    pass
</code></pre>

<p>and </p>

<pre><code>&gt;&gt;&gt; isinstance(Hello,object)
True
&gt;&gt;&gt; issubclass(Hello,object)
False
&gt;&gt;&gt; a = Hello()
&gt;&gt;&gt; isinstance(a,object)
True
</code></pre>

<p>How do you explain <code>isinstance(Hello,object)</code> returns <strong>True</strong> whilst <code>issubclass(Hello,object)</code> returns <strong>False</strong></p>
