Bump PYTHON3_VERSION_MIN #15665
Description
Feature
Right now mypy says:
» mypy mypy/stubgen.py --python-version=3.2
usage: mypy [-h] [-v] [-V] [more options; see below]
[-m MODULE] [-p PACKAGE] [-c PROGRAM_TEXT] [files ...]
mypy: error: argument --python-version: Python 3.2 is not supported (must be 3.4 or higher)
But, it does not look correct, because typeshed does not support 3.4 (currently it supports 3.7+).
So, how mypy can check 3.4?
I think that we need to bump it:
3.4is long gone- We don't actually plan any features with this support in mind
typsheddoes not support it- Users that need it can stay on older versions
Pitch
Let's use 3.7 as the minimal supported version. (Ideas about it are welcome)
After we decide the version info to be minimal, I will send a PR with the change :)

I think this is a great suggestion. I think it would make sense to intend to support all current active versions (leeway for new releases) and the last end-of-life version of Python.
That allows mypy to move forward without carrying the baggage of legacy code.
That would align with the suggestion of 3.7 per:

Good spot! Yeah, I'd go with whatever the vendored version of typeshed supports, so 3.7 currently.
