<h1>Flask</h1>
<p><a href="http://flask.pocoo.org/">Flask</a> is a Python web framework built with a
<a href="http://flask.pocoo.org/docs/design/">small core and easy-to-extend philosophy</a>.
<a href="http://flask.pocoo.org/" style="border: none;"><img src="theme/img/flask.png" width="100%" alt="Official Flask logo. Flask Artwork License." class="technical-diagram" /></a></p>
<h2>Why is Flask a good web framework choice?</h2>
<p>Flask is considered more
<a href="http://blog.startifact.com/posts/older/what-is-pythonic.html">Pythonic</a>
than Django because Flask web application code is in most cases more explicit.
Flask is easy to get started with as a beginner because there is little
boilerplate code for getting a simple app up and running. </p>
<p>For example, here's a valid "hello world" web application with Flask (the
equivalent in Django would be significantly more code):</p>
<div class="codehilite"><pre><span class="n">from</span> <span class="n">flask</span> <span class="n">import</span> <span class="n">Flask</span>
<span class="n">app</span> <span class="o">=</span> <span class="n">Flask</span><span class="p">(</span><span class="n">__name__</span><span class="p">)</span>
<span class="err">@</span><span class="n">app</span><span class="p">.</span><span class="n">route</span><span class="p">(</span><span class="sc">'/'</span><span class="p">)</span>
<span class="n">def</span> <span class="n">hello_world</span><span class="p">()</span><span class="o">:</span>
<span class="k">return</span> <span class="err">'</span><span class="n">Hello</span> <span class="n">World</span><span class="o">!</span><span class="err">'</span>
<span class="k">if</span> <span class="n">__name__</span> <span class="o">==</span> <span class="err">'</span><span class="n">__main__</span><span class="err">'</span><span class="o">:</span>
<span class="n">app</span><span class="p">.</span><span class="n">run</span><span class="p">()</span>
</pre></div>
<p>Flask was also written several years after Django and therefore
learned from the Python community's reactions as the framework evolved.
Jökull Sólberg wrote a great piece articulating to this effect in his
<a href="http://jokull.calepin.co/my-flask-to-django-experience.html">experience switching between Flask and Django</a>.</p>
<h2>Flask resources</h2>
<p>The 18-part Flask mega tutorial is an absolutely amazing starting
resource for using the Flask framework. Yes, there are a lot of posts in
the series. However, each post is focused on a single topic to contain
the complexity while the reader is learning the framework. The whole
series is well worth an in-depth read-through. The
<a href="https://twitter.com/miguelgrinberg">author</a> also wrote the new
<a href="http://shop.oreilly.com/product/0636920031116.do">O'Reilly Flask Web Development</a>
book which is an excellent learning resource.</p>
