So I now have both Python 2.7.18 and 3.8.9 pre-installed on my MacBook Pro with Monterey (Does macOS Monterey come with Python3 preinstalled?).

But how can I launch IDLE3? When I issued the command "idle3" in Terminal, it returned "command not found: idle3". Does it mean that IDLE3 hasn't been pre-installed along with Python3?

In addition, should I install the most updated version of Python?

I am trying to learn Python. Thanks for any help.

The system python doesn't come with IDLE, since it's there to support system functions primarily.

Install your own copy, either with the official installers, or with homebrew or similar.
