title: How to get back to python virtual environment in mac command line
body: <p>I am having a bit of difficulty reinitiating my virtual environment on my preprod server on command line. I think when I quit out of my preprod server the other day, I also quit out of my virtual environment, because now it doesn't say (env) in front of the preprod prompt:</p>
  
  <pre><code>Before: (env) SAS@preprod:~$
  Now: SAS@preprod:~$
  </code></pre>
  
  <p>I am logged into my preprod server now, and I have a virtual_environment_command.txt file, and a config file accessible. I just don't know how to activate either of those documents so I can utilize my virtual environment for testing the code for an api document I'm working on. Thanks!</p>
