<p id="index-1">The <a class="reference internal" href="#module-glob" title="glob: Unix shell style pathname pattern expansion."><code class="xref py py-mod docutils literal notranslate"><span class="pre">glob</span></code></a> module finds all the pathnames matching a specified pattern
according to the rules used by the Unix shell, although results are returned in
arbitrary order. No tilde expansion is done, but <code class="docutils literal notranslate"><span class="pre">*</span></code>, <code class="docutils literal notranslate"><span class="pre">?</span></code>, and character
ranges expressed with <code class="docutils literal notranslate"><span class="pre">[]</span></code> will be correctly matched. This is done by using
the <a class="reference internal" href="os.html#os.scandir" title="os.scandir"><code class="xref py py-func docutils literal notranslate"><span class="pre">os.scandir()</span></code></a> and <a class="reference internal" href="fnmatch.html#fnmatch.fnmatch" title="fnmatch.fnmatch"><code class="xref py py-func docutils literal notranslate"><span class="pre">fnmatch.fnmatch()</span></code></a> functions in concert, and
not by actually invoking a subshell. Note that unlike <a class="reference internal" href="fnmatch.html#fnmatch.fnmatch" title="fnmatch.fnmatch"><code class="xref py py-func docutils literal notranslate"><span class="pre">fnmatch.fnmatch()</span></code></a>,
<a class="reference internal" href="#module-glob" title="glob: Unix shell style pathname pattern expansion."><code class="xref py py-mod docutils literal notranslate"><span class="pre">glob</span></code></a> treats filenames beginning with a dot (<code class="docutils literal notranslate"><span class="pre">.</span></code>) as special cases.
(For tilde and shell variable expansion, use <a class="reference internal" href="os.path.html#os.path.expanduser" title="os.path.expanduser"><code class="xref py py-func docutils literal notranslate"><span class="pre">os.path.expanduser()</span></code></a> and
<a class="reference internal" href="os.path.html#os.path.expandvars" title="os.path.expandvars"><code class="xref py py-func docutils literal notranslate"><span class="pre">os.path.expandvars()</span></code></a>.)</p>
<p>For a literal match, wrap the meta-characters in brackets.
For example, <code class="docutils literal notranslate"><span class="pre">'[?]'</span></code> matches the character <code class="docutils literal notranslate"><span class="pre">'?'</span></code>.</p>

<p>The <a class="reference internal" href="pathlib.html#module-pathlib" title="pathlib: Object-oriented filesystem paths"><code class="xref py py-mod docutils literal notranslate"><span class="pre">pathlib</span></code></a> module offers high-level path objects.</p>

<p id="index-2">If <em>recursive</em> is true, the pattern “<code class="docutils literal notranslate"><span class="pre">**</span></code>” will match any files and zero or

This is useful if you want to match an arbitrary literal string that may
have special characters in it. Special characters in drive/UNC
sharepoints are not escaped, e.g. on Windows
<code class="docutils literal notranslate"><span class="pre">escape('//?/c:/Quo</span> <span class="pre">vadis?.txt')</span></code> returns <code class="docutils literal notranslate"><span class="pre">'//?/c:/Quo</span> <span class="pre">vadis[?].txt'</span></code>.</p>

the following results. Notice how any leading components of the path are
