<p>A lot of useful features in Python are somewhat "hidden" inside modules. Named tuples (new in <a href="http://docs.python.org/whatsnew/2.6.html" rel="nofollow noreferrer">Python 2.6</a>), for instance, are found in the <a href="http://docs.python.org/library/collections.html" rel="nofollow noreferrer">collections</a> module. </p>

<p>The <a href="http://docs.python.org/library/" rel="nofollow noreferrer">Library Documentation page</a> will give you all the modules in the language, but newcomers to Python are likely to find themselves saying "Oh, I didn't know I could have done it <em>this way</em> using Python!" unless the important features in the language are pointed out by the experienced developers.</p>

<p>I'm <strong>not</strong> specifically looking for new modules in Python 2.6, but modules that can be found in this latest release.</p>

May be
PEP 0631
and
What's new in 2.6
can provide elements of answer. This last article explains the new features in Python 2.6, released on October 1 2008.
