Even though Python 2 has been end-of-life’d on January 1st, 2020, we have until now been providing IDAPython builds that can run on a Python 2 runtime.
But usage of Python 2 runtimes has been discouraged for a while now

In order to free us of that cost, we have decided to drop support for Python 2 in the next IDA releases (7.8 onward.) We trust that, by now, the impact for our users will be minimal.
