title: how to create a python virtualenv environment without prompt prefix?
body: <p>I want to have a "default" virtual environment, and for such I don't want to have a prompt prefix. The following option allows one to customize the prompt prefix for for a given environment:</p>
  
  <pre><code>--prompt=PROMPT       Provides an alternative prompt prefix for this environment
  </code></pre>
  
  <p>But I couldn't figure out how to use it to set an empty prefix. Is there a way for that?</p>
  
  <p>I was using <code>VIRTUAL_ENV_DISABLE_PROMPT</code> to disable prompt prefix globally, but I changed my mind once I came to know the <code>--prompt</code> option. I want to choose the environment to have no prefix.</p>
