<p style="color: grey"> Python recipe 578073 by <a href="/recipes/users/4172918/">Daniel Cohn</a> (<a href="/recipes/tags/debugging/">debugging</a>, <a href="/recipes/tags/decorator/">decorator</a>, <a href="/recipes/tags/pdb/">pdb</a>, <a href="/recipes/tags/redirect/">redirect</a>, <a href="/recipes/tags/robot/">robot</a>, <a href="/recipes/tags/rpdb/">rpdb</a>, <a href="/recipes/tags/stdin/">stdin</a>, <a href="/recipes/tags/stdout/">stdout</a>). </p> <p>Robotframework (<a href="http://code.google.com/p/robotframework/" rel="nofollow">http://code.google.com/p/robotframework/</a>) is a tool used to run functional tests against a variety of targets. Tests are organized in the form of keyword tsv or html files, which map input parameters to keyword-argument methods in the test suite. Robot includes a fairly advanced logging mechanism, which is cool -- until you try to debug anything. Debugging is made difficult because robot steals stdin and stdout when it is run, which means bye-bye debugging in the terminal. rpdb solves this in a KISS simple way.</p>

Revision 2. </p> <p>This recipe provides a decently simple implementation of a roundrobin using itertools and deque.</p>

<p style="color: grey"> Python recipe 577196 by <a href="/recipes/users/4172918/">Daniel Cohn</a> (<a href="/recipes/tags/generator/">generator</a>, <a href="/recipes/tags/iterable/">iterable</a>, <a href="/recipes/tags/iterator/">iterator</a>, <a href="/recipes/tags/loop/">loop</a>, <a href="/recipes/tags/peeking/">peeking</a>, <a href="/recipes/tags/window/">window</a>). </p> <p>Oftentimes a programmer needs to peek into an iterator without advancing it, a task for which many good solutions already exist. But what if the intrepid coder needs a fast and pythonic way to 'window' the data? This recipe demonstrates how to wrap any iterable with a class that adds two methods, prev and peek.</p>

Revision 2. </p> <p>Walks subdirectories to find a file and returns . Default start location is the current working directory. Optionally, a different directory can be set as the search's starting location.</p>

Each line in the stdout will have its line number prepended.</p>
