title: Django how to phasing the dollar sign using os.environ.get( )
body: <p>I'm coding Django program,code is running in Linux, the env file includes :</p>
  <pre><code> &quot;PWD=uTfa$aB67&quot;
  </code></pre>
  <p>in settings.py:</p>
  <pre><code>PWD = os.environ.get('PWD')
  </code></pre>
  <p>Then in the code where I need this password ,I code:</p>
  <pre><code>password = settings.PWD
  </code></pre>
  <p>However every time when I print 'password' ,I only got:</p>
  <pre><code>uTfa
  </code></pre>
  <p>I have tried single quotes ,but it not works. Any suggestion ?</p>
