I am trying to get userStory value from user while running build pipeline in Azure DevOps. I want to use that value as a variable into the python script that I am building. I tried below code with yaml, Also attached is the error.

trigger:
- main

pool:
  vmImage: 'ubuntu-latest'

parameters:
  - name: UserStory
    displayName: Enter User Story ID.
    type: string
    default: ''

steps:
- task: UsePythonVersion@0
  inputs:
    versionSpec: '3.x'
    addToPath: true
  
- script: |
    echo "Running p1.py with User Story ID ${UserStory}"
    export USER_STORY_ID=${UserStory}
    python p1.py
  displayName: 'Run p1.py'

p1.py

import os

print('Hello, world!')
user_story2 = os.getenv('USER_STORY_ID')
print(user_story2)

    The right syntax to use a parameter is ${{ parameters.xxx }}.

    Also, you don’t need to set the environment variable in the script body using the export command.

    Set an environment variable at the task level instead:

    - script: |
    echo "Running p1.py with User Story ID ${{ parameters.UserStory }}"
    python p1.py
  displayName: 'Run p1.py'
  env:
   USER_STORY_ID: ${{ parameters.UserStory }}

    As mentioned by @Rui Jarimba and in this question, the syntax to read parameters is ${{parameters.name}}. See the details from Runtime parameters.

    Updated YAML:

    - script: |
    echo "Running p1.py with User Story ID ${{parameters.UserStory}}"
    export USER_STORY_ID=${{parameters.UserStory}}
    python p1.py
  displayName: 'Run p1.py'

    Result:
