When running cfn on Python 3.12, it throws this syntax error:

$ cfn --version

How did you install Python, and how are you running cfn-cli?

If cfn-cli or Python was installed via brew, I noticed this occurring with many of my tools that used the brew python as the base environment after an update to Python. I use pipx and reinstalled all tools with a 3.12 runtime created by pyenv.

I had to reinstall python from scratch to resolve the issues I was facing for the tools that do not work well within pipx.

I installed it with pip install cloudformation-cli using my homebrew python
