Is Python 3.9 still supported?

[JarLob]

Trying local deployment. Ran python3.9 -m pipenv shell ang got this error. The internet search says the syntax requires 3.10 or later.

Asking because of these lines:

clusterfuzz/local/install_deps_linux.bash

Lines 30 to 35 in 44d02ae

	elif which python3.10 > /dev/null; then
	export PYTHON='python3.10'
	elif which python3.9 > /dev/null; then
	export PYTHON='python3.9'
	elif which python3.8 > /dev/null; then
	export PYTHON='python3.8'
