Passing arguments to python script in Azure Devops

I am trying to pass a system variable to the python script from azure devops. This is what I currently have in Yaml file: 

- script: pytest test/test_pipeline.py 
          --$(global_variable) 
          --junitxml=$(Build.StagingDirectory)/test_pipeline-results.xml
          displayName: 'Testing Pipeline'
          condition: always()

The variable I need in my script is $(global_variable). The variable contains a value of $(Build.SourcesDirectory). It is the global variable. I am getting an error message as "unrecognised arguments" when I run the job.

Any help to tackle this will be helpful.

Thanks!

I tried to write a simple sample for you refer.

In your .py file, please use add_argument to read in the command line parameter. In this issue, this command line parameter comes from your task specified.

A.py file:

import argparse 

def parse_argument():
       parse = argparse.ArgumentParser(description="ForTest!")
       parse.add_argument("-test_data")
       parse.add_argument("-build_dir")

And then, in PythonScript@0 task:

scriptPath: ‘A.py’
argument: -test_data $(myVariable1) -build_dir $(myVariable2)

myVariable1 and myVariable2 are all my customized variable. You can all use environment variable.

Since in python script, add_argument is used to read in the parameter which from command line. So it can receive the value from Argument specified.

In addition, for the issue which in your question, I think you’d better delete the content from your script: --my_param="/home/vsts/work/1/s" and try again. Because --my_param could not the valid argument for pytest.

Hope can help you.
