<p style="color: grey"> Python recipe 577083 by <a href="/recipes/users/4173218/">pwaller</a> (<a href="/recipes/tags/contextmanager/">contextmanager</a>, <a href="/recipes/tags/freopen/">freopen</a>, <a href="/recipes/tags/silence/">silence</a>, <a href="/recipes/tags/stdout/">stdout</a>, <a href="/recipes/tags/with/">with</a>). Revision 2. </p> <p>Fed up with libraries you don't have control over emitting text into your precious stdout?</p> <p>If they use stdout through python, then you can just change sys.stdout to be something else. If they are printing directly to stdout through a C module, or some other means, then you are stuck.</p> <p>.. at least until you discover the <code>with silence():</code> block!</p> <p>Caveats: Non-portable, tested only on 2.6 under Linux, uses threading.</p> <p>Example output:</p> <pre class="prettyprint"><code>$ python silence_file.py Before with block.. Sensible stuff! After the silence block </code></pre>
