setting “python_requires” with ">=3.6.2" is a better way to declare Python compatibility

[PyVCEchecker]

Hello!
I noticed such a declaration in setup.py

classifiers=[
        "Programming Language :: Python :: 3.6",
        "Programming Language :: Python :: 3.7",
        "Programming Language :: Python :: 3.8",
        "Programming Language :: Python :: 3.9",
   ...
   ]

and the dependency "pylint-plugin-utils>=0.7" has a declaration "requires_python": ">=3.6.2",
so I guess you want to set python>3.6.2. And I think it is a better way to declare Python compatibility by using the keyword argument python_requires than argument classifiers for some reasons:

• Descriptions in python_requires will be reflected in the metadata
• “pip install” can check such metadata on the fly during distribution selection , and prevent from downloading and installing the incompatible package versions.
• If the user does not specify any version constraint, pip can automatically choose the latest compatible package version for users.

Way to improve:
modify setup() in setup.py, add python_requires keyword argument:

setup(…
     python_requires=">=3.6.2",
     …)

Thanks for your attention.
Best regrads,
