:: in strings in Python
<p>I've been learning Python and I must say I loved it. But as a new learners I am having some other problems as well:</p>

<p>Could you guys tell me whether it is a feature of Python or the library of itself.</p>

<p>I am checking how to connect to sqllite database and I came up with this article and there is a code sample over there as such below:</p>

<pre><code>&gt;&gt;&gt; from pysqlite2 import dbapi2 as sqlite
&gt;&gt;&gt; connection = sqlite.connect('test.db')
&gt;&gt;&gt; memoryConnection = sqlite.connect(':memory:')
&gt;&gt;&gt; cursor = connection.cursor()
</code></pre>

<p>When he wrote memory as string, he put two <code>:</code> (colon) as well and I am wondering whether it is peculiar to library instead of Python itself.</p>
