title: How to use Jenkins Environment variables in python script
body: <p>so I have a bash script in which I use the environment variables from Jenkins 
  for example:
   QUALIFIER=<code>echo $BUILD_ID | sed "s/[-_]//g" | cut -c1-12</code></p>
  
  <p>Essentially I'm taking the build id, along with job name to determine which script to call from my main script. I want to use python instead so I was wondering whether I can use these variables without the jenkins python api.</p>
  
  <p>I hope the question makes sense. Thanks</p>
