Default python new version not seen

Hello, I have installed python 3.9.1 and indeed this is confirmed in the terminal when looking to the version. However when launching Biopython I get the message "Biopython requires Python 3.6 or later. Python 2.7 detected." How is this possible? What to do? Thanks.

Python is generally symlinked to python v.2.x. Can you explicitly try `python3`?

New python versions usually break a lot of modules, especially low-level ones like pyinstaller and cffi. I usually wait for a revision or two before upgrading to let module maintainers catch up. Waiting also lets the PSF fix any bugs and security holes that are bound to be lurking somewhere.
