I built a pylint git action, for pull request, which actually works really well:

name: Python Linting

on:
  pull_request:
    branches: [ main, dev ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Setup action
      uses: actions/checkout@v2
      with:
        ref: ${{github.event.pull_request.head.ref}}
        repository: ${{github.event.pull_request.head.repo.full_name}}
    - name: Set up Python 3.10
      uses: actions/setup-python@v2
      with:
        python-version: "3.10"
    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
    - name: Changed Files Exporter
      id: files
      uses: umani/[email protected]
      with:
        repo-token: ${{ github.token }}
        pattern: '^src.*\.(py)$'
        result-encoding: 'string'
    - name: Lint with pylint
      working-directory: ./
      run: |
        echo  '${{ steps.files.outputs.files_updated }} ${{ steps.files.outputs.files_created }}'
        pip install pylint
        OUTPUT=$(pylint ${{ steps.files.outputs.files_updated }} ${{ steps.files.outputs.files_created }} --exit-zero)
        echo 'MESSAGE<<EOF' >> $GITHUB_ENV
        echo  "$OUTPUT"  >> $GITHUB_ENV
        echo 'EOF' >> $GITHUB_ENV
    - name: Post result to PR
      uses: mshick/add-pr-comment@v1
      with:
