“python_requires” should be set with “>=3.6, <3.10”, as zappa 0.54.1 is not compatible with all Python versions.

Currently, the keyword argument python_requires of setup() is not set, and thus it is assumed that this distribution is compatible with all Python versions.
However, I found the following code checking Python compatibility locally in zappa/__init__.py

SUPPORTED_VERSIONS = [(3, 6), (3, 7), (3, 8), (3, 9)]

if sys.version_info[:2] not in SUPPORTED_VERSIONS:
    ……
    raise RuntimeError(err_msg)

I think it is a better way to declare Python compatibility by using the keyword argument python_requires than checking compatibility locally 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, <3.10",
     …)

Thanks for your attention.

python 3.6 support was removed, but python_requires was added.
released, closing.
