Build marked as failing. Tests are not running in CI. Github /actions/setup-python no longer supports Python 2.7.

The issue already occurs, due to PyShps's own CI code/config/setup. In particular the Github action file below:

Other notes

In June 2023, Python 2 was dropped by /actions/setup-python actions/setup-python#672

A work around to run the action in a container, is suggested in the comments by tzortzispanagiotis (the proviso about localhost is not relevant to PyShp as it does not do any networking): actions/setup-python#672 (comment)

I'll investigate using that with the actions matrix.
Python 2 is no longer pre-installed in current Actions Runner Ubuntu images (19.04 having been dropped?).

The suggestion from tzortzispanagiotis works great with a matrix strategy, for PyShp.

Using this, the CI can be fixed, simply by replacing all the lines in the above file between:

jobs:
  build:

and

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip

(exclusive) with:

    strategy:
      fail-fast: false
      matrix:
        python-version: ["2.7.18", "3.6.15", "3.7.17", "3.8.18", "3.9.18", "3.10.13", "3.11.7", "3.12.1", "3.13.0a2"]

    runs-on: ubuntu-20.04
    container:
      image: python:${{ matrix.python-version }}-slim

    steps:
    - uses: actions/checkout@v3

I have tested this on my fork, but could only get a green tick for Python 2.7 as well, by disabling __geo_interface__, and all the tests for it, and for Pythons 3.10 upwards by relaxing the pinned version of Pytest, allowing Pip to pick the latest (and possibly by making other changes that don't spring to mine right now):
