Python version

[turbomam]

There are inconsistent minimum Python version in various files. This is kinda in flux as I prepare the PRs for branches issue_84_reintegrate and issue-69-pypi. As part of that or immediately after it... change everything to 3.x? 3.7? 3.8?

I think this is the state in main as of now:

• setup.cfg says python_requires = >=3.7
• setup.py says if sys.version_info < (3, 7, 0):
  • in the branches above, I modified the reporting of warning string due to a error when trying to run setup.py under 2.7
• tox.ini says envlist = py37, py38, py39
• ./Pipfile says python_version = "3.8" ?

As far as I know, we've now standardized to a minimum version of Python 3.7 everywhere.

I think we've standardized to Python 3.7 everywhere as of PR #75. Closing, but please reopen if I'm wrong.
