<p style="color: grey"> Python recipe 580759 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/commandline/">commandline</a>, <a href="/recipes/tags/introspection/">introspection</a>, <a href="/recipes/tags/libraries/">libraries</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/unix/">unix</a>, <a href="/recipes/tags/utilities/">utilities</a>, <a href="/recipes/tags/windows/">windows</a>). </p> <p>This recipe is a simple Python introspection utility that displays the defined OS error codes and messages (that Python knows about) from the os.errno module. It works for both Python 2 and Python 3. For each kind of OS error defined in Python, it will display a serial number, the error code, and the corresponding error name, and English error message. E.g. the first few lines of its output are shown below:</p> <p>$ py -2 os_errno_info.py</p> <p>Showing error codes and names</p> <p>from the os.errno module:</p> <p>Python sys.version: 2.7.12</p> <p>Number of error codes: 86</p> <p>Idx Code Name Message</p> <p>0 1 EPERM Operation not permitted</p> <p>1 2 ENOENT No such file or directory</p> <p>2 3 ESRCH No such process</p> <p>3 4 EINTR Interrupted function call</p> <p>4 5 EIO Input/output error</p> <p>More information, full output and other details are available here:</p> <p><a href="https://jugad2.blogspot.in/2017/03/show-error-numbers-and-codes-from.html" rel="nofollow">https://jugad2.blogspot.in/2017/03/show-error-numbers-and-codes-from.html</a></p>
