title: module 'os' has no attribute 'add_dll_directory' python 3.8
body: <p>I am trying to use confluent_kafka:1.6.0 module in aws lambda function and in the <strong>init</strong> file in line 9 they have the following statement:
  <code>os.add_dll_directory(libs_dir)</code> which is used to import some dll file that the module need, but I keep getting an error that say: <code>&quot;errorMessage&quot;: &quot;module 'os' has no attribute 'add_dll_directory'&quot;</code>.
  Facts:</p>
  <ol>
  <li>os module does exist.</li>
  <li>sys exist with version:3.8.8 <code>sys.version_info(major=3, minor=8, micro=8, releaselevel='final', serial=0)</code></li>
  <li>All my python libraries are in a separate layer from my lambda function</li>
  <li>When I display function of os, add_dll_library doesn't come back as part of the list</li>
  </ol>
  <p>Anyone got an idea of what why os does not have that method? and would I fix that in AWS lambda?</p>
