How to use Jenkins Environment variables in python script

Question

so I have a bash script in which I use the environment variables from Jenkins for example: QUALIFIER=echo $BUILD_ID | sed "s/[-_]//g" | cut -c1-12

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.

I hope the question makes sense. Thanks

I need to use the environment variables in Jenkins such as JOB_NAME to decide which script to call. I have a bash script which gets these variables but I wanted to do this in a python script. How would I get these variables in python? — Asad S. Malik

That's what you need if I understand you correctly:

QUALIFIER="$(echo $BUILD_ID | sed "s/[-_]//g" | cut -c1-12)"
export QUALIFIER
python my_script.py

And in your Python script:

import os
qualifier = os.environ['QUALIFIER']

or without the shell part:

import os
import re
qualifier = re.sub(r'[-_]+', '', os.environ['BUILD_ID'])[0:12]

But would I need my bash script as well as the python one takes the 'QUALIFIER'? The $BUILD_ID makes the jenkins environment variable available to the bash script. Is there somehow I can make it available to the python script without having to use the bash one?

You can access $BUILD_ID exactly the same way (using os.environ) and then remove dashes and slice it in Python.

import os

os.environ.get("variable_name")
