This module228also allows an item of <code class="xref py py-data docutils literal notranslate"><span class="pre">sys.path</span></code> to be a string naming a ZIP file archive.229The ZIP archive can contain a subdirectory structure to support package imports,230and a path within the archive can be specified to only import from a231subdirectory. For example, the path <code class="file docutils literal notranslate"><span class="pre">example.zip/lib/</span></code> would only232import from the <code class="file docutils literal notranslate"><span class="pre">lib/</span></code> subdirectory within the archive.</p>233<p>Any files may be present in the ZIP archive, but importers are only invoked for234<code class="file docutils literal notranslate"><span class="pre">.py</span></code> and <code class="file docutils literal notranslate"><span class="pre">.pyc</span></code> files. ZIP import of dynamic modules235(<code class="file docutils literal notranslate"><span class="pre">.pyd</span></code>, <code class="file docutils literal notranslate"><span class="pre">.so</span></code>) is disallowed.
