title: how to find the target file's full(absolute path) of the symbolic link or soft link in python
body: <p>when i give 
  ls -l /etc/fonts/conf.d/70-yes-bitmaps.conf </p>
  
  <pre><code>lrwxrwxrwx &lt;snip&gt; /etc/fonts/conf.d/70-yes-bitmaps.conf -&gt; ../conf.avail/70-yes-bitmaps.conf
  </code></pre>
  
  <p>so for a symbolic link or soft link, how to find the target file's full(absolute path) in python,</p>
  
  <p>If i use </p>
  
  <p><code>os.readlink('/etc/fonts/conf.d/70-yes-bitmaps.conf')</code></p>
  
  <p>it outputs </p>
  
  <p><code>../conf.avail/70-yes-bitmaps.conf</code></p>
  
  <p>but i need the absolute path not the relative path, so my desired output must be,</p>
  
  <p><code>/etc/fonts/conf.avail/70-yes-bitmaps.conf</code></p>
  
  <p>how to replace the <code>..</code> with the actual full path of the parent directory of the symbolic link or soft link file.</p>
