Python IDLE

IDLE is Python’s Integrated Development and Learning Environment where it allows programmers to easily write Python code. It's like a shell, you can execute a single statement or create/execute a Python script.

If you see below error message when you try to run IDLE, it's most likely you are missing tk USE flag for python.

idle: no python-exec wrapped executable found in /usr/lib/python-exec

To check if you are missing the tk USE flag, first check the python version:$ eselect python list Available Python interpreters, in order of preference: [1] python3.8 [2] python3.9 (fallback)

Also, check the system configuration file, /etc/python-exec/python-exec.conf, for python version:

Then, execute emerge with the following flags to see if tk USE flag was enabled originally. In below case, tk is not enabled since it's -tk.# emerge -pve world | grep -i dev-lang/python-3.8 [ebuild R ] dev-lang/python-3.8.8:3.8::gentoo USE="gdbm ipv6 ncurses readline sqlite ssl xml -bluetooth -build -examples -hardened (-libressl) -test -tk -verify-sig -wininst" 0 KiB

To enable the flag, you need to re-run emerge with the tk flag.# USE=tk emerge -a dev-lang/python:3.8

After successful update, check if it's enabled by running the same command: # emerge -pve world | grep -i dev-lang/python-3.8 [ebuild R ] dev-lang/python-3.8.8:3.8::gentoo USE="gdbm ipv6 ncurses readline sqlite ssl tk xml -bluetooth -build -examples -hardened (-libressl) -test -verify-sig -wininst" 0 KiB

That's all!
