(<a href="/recipes/tags/benchmark/">benchmark</a>, <a href="/recipes/tags/speed/">speed</a>, <a href="/recipes/tags/time/">time</a>, <a href="/recipes/tags/timer/">timer</a>).
</p>
<p>Inspired by <a href="http://preshing.com/20110924/timing-your-code-using-pythons-with-statement">this post</a> I wrote this context manager to benchmark code blocks or function calls.</p>
<p>Usage is incredibly simple:</p>
<pre class="prettyprint"><code>with Timer():
... # code to benchmark goes here
</code></pre>
<p>The time taken (in seconds) will be printed when the code block completes. To capture the time taken programmatically is almost as easy:</p>
<pre class="prettyprint"><code>t = Timer()
with t:
... # code to benchmark goes here
time_taken = t.interval
</code></pre>
<p>Due to the difficulties of timing small snippets of code <em>accurately</em>, you should only use this for timing code blocks or function calls which take a significant amount of time to process. For micro-benchmarks, you should use the <code>timeit</code> module.</p>
