I would like to configure Atom to run Python3 scrip
If you are using Atom on Mac OS and have script 3.18.1 and atom-python-run 0.9.7 packages installed, the following steps will help you out.
Script-> Configure Script
Then type in Python3 in the command field in the options dialog.
This should solve your problem.
