<p style="color: grey"> Python recipe 577564 by <a href="/recipes/users/4176881/">Greg Haskins</a> (<a href="/recipes/tags/contextmanager/">contextmanager</a>, <a href="/recipes/tags/context_manager/">context_manager</a>, <a href="/recipes/tags/f2py/">f2py</a>, <a href="/recipes/tags/fortran/">fortran</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/redirect/">redirect</a>, <a href="/recipes/tags/stdout/">stdout</a>). Revision 3. </p> <p>This context manager provides a convenient, Pythonic way to temporarily replace the file descriptors of <code>stdout</code> and <code>stderr</code>, redirecting to either <code>os.devnull</code> or files of your choosing. Swapping the C-level file descriptors is required when suppressing output from compiled extension modules, such as those built using F2PY. It functions equally well for pure-Python code. <em>UPDATE:</em> (see below).</p>
