Access variables from Variable Groups inside Python script task in Azure DevOps Yaml pipeline

Question

I'm using a Python script task of type 'file' in my Azure DevOps Yaml pipeline. I need to use the variables that I defined in my Variable Group in the Python file. The following is my task on Azure devops yaml pipeline.

  - task: PythonScript@0
    displayName: 'Run a Python script'
    inputs:
      scriptPath: 'pythonTest.py'

Any advise on how I can achieve this?

Thanks!

You need to pass the variables to the script, using arguments, and you of course need to reference the variable group:

variables:
- group: variableGroup

steps:
  - task: PythonScript@0
    displayName: 'Run a Python script'
    inputs:
      scriptPath: 'pythonTest.py'
      arguments: --variableInScript $(variableInVariableGroup)

And then use 'argparse' in the script.

If you were using an inline script you could have done it like this:

- task: PythonScript@0
  inputs:
    scriptSource: 'inline'
    script: |
      print('variableInVariableGroup: $(variableInVariableGroup)')
