Python3 command not found

Oh, but my config asks for both?

    working_directory: ~/workspace
    docker:
      - image: circleci/node:8.11.1
      - image: circleci/python:3.7.2

Basically I have a monorepo with many independent projects.

I have a simple python3 script I want to run that checks what sets of tests / lints / checkstyles need to be run, depending on what folders have changed. So if you’re only changing folder A, run tests A, and if changing folder B, run tests B, etc.

I’ve validated this script works, but lo and behold when I try to run it on python 3, it fails. And python --version shows Python 2.7.9

EDIT: We also have python in our repo, so I just defaulted to python3 so that we could have all our codebase run a single version fo python, with those same style checkers, etc. So it’s definitely not a blocker if I have to write a python2 script for this.
