<p style="color: grey"> Python recipe 577817 by <a href="/recipes/users/4178764/">Giampaolo Rodolà</a> (<a href="/recipes/tags/profile/">profile</a>, <a href="/recipes/tags/profiling/">profiling</a>, <a href="/recipes/tags/python/">python</a>). </p> <p>A decorator for profiling a function which prints profiling results to stdout. This was originally proposed as a patch for inclusion into python stdlib:</p> <p><a href="http://bugs.python.org/issue9285" rel="nofollow">http://bugs.python.org/issue9285</a></p> <p>Note that on certain Linux systems pstats module isn't available, despite it is supposed to be part of Python stdlib. On my Ubuntu box I had to run "sudo apt-get install python-profile" first.</p>

<p style="color: grey"> Python recipe 576656 by <a href="/recipes/users/4173505/">Trent Mick</a> (<a href="/recipes/tags/hotshot/">hotshot</a>, <a href="/recipes/tags/performance/">performance</a>, <a href="/recipes/tags/profile/">profile</a>). Revision 2. </p> <p>This is a quick snippet that I use occasionally to profile some pure-Python code, using <a href="http://docs.python.org/library/hotshot.html#module-hotshot"><code>hotshot</code></a>. Basically it is this:</p> <ol> <li>Put this <code>@hotshotit</code> decorator on the function you want to profile.</li> <li>Run your code through some representative paces. The result will be a <code>&lt;functionname&gt;.prof</code> in the current directory.</li> <li>Process the <code>.prof</code> file and print the top 20 hotspots with the given "show_stats.py" script.</li> </ol> <p>Props to <a href="http://blogs.activestate.com/toddw/">Todd</a> for slapping this code together.</p> <p>Hotshot <a href="http://docs.python.org/library/profile.html">is a little out of favour</a> now, so I should -- or Todd :) -- should really come up with an equivalent that uses <code>cProfile</code>.</p>
