Loading python3 on Archlinux

sudo pacman -S python3

sudo pacman -S tk

But  loading tk would not work correctly..don't know why.

Had to download individual files from http://mirror.lug.udel.edu/pub/archlinuxarm/aarch64/extra/
I did this by editing the pacman mirrorlist and adding the above url to the mirrorlist
The mirror list is located here: /etc/pacman.d/mirrorlist

The files I installed were:
tk-8.6.8-2-aarch64.pkg.tar.xz
tcl-8.6.8-2-aarch64.pkg.tar.xz'

Ran into some bug when trying to run idle in command line (e.g.>> idle)

This fixed it

Looks like a Archlinux bug affecting TK gui applications. Clearing out the X resources fixes the problem:
$ xrdb -load /dev/null
$ xrdb -query
