This section recommends several tools: https://docs.python.org/3/howto/pyporting.html#how-to-port-python-2-code-to-python-3

Including:

• pylint: Drop support for Python 2 pylint-dev/pylint#1763
• coverage: https://pypi.org/project/coverage/ (python3 only)
• mypy: Python 2 feature freeze (and removal of support) mypy#12237
• tox: dropping Python 2 support for tox host python tox-dev/tox#1130

But, these tools do not support Python2 anymore, so users will probably struggle with this advice.
