<p style="color: grey"> Python recipe 580745 by <a href="/recipes/users/4182236/">Alfe</a> (<a href="/recipes/tags/aspect/">aspect</a>, <a href="/recipes/tags/except/">except</a>, <a href="/recipes/tags/exception/">exception</a>, <a href="/recipes/tags/retry/">retry</a>, <a href="/recipes/tags/try/">try</a>). </p> <p>This is a Python decorator which helps implementing an aspect oriented implementation of a <em>retrying</em> of certain steps which might fail sometimes. A typical example for this would be communication processes with the outside world, e. g. HTTP requests, allocation of some resource, etc. To use it, refactor the step in question into a (local) function and decorate this with the <code>retry</code> decorator. See examples in the discussion sector below.</p>
