My codes are running successfully, Thanks Code.cademy.
Basing on this "Who needs to pay for grade calculation software when you can write your own? :)", how can i save these codes using my IDLE (Python 3.6 32-bit) on my laptop to use it to calculate my students grades? i am a teacher . Thanks in advance for your guidance. any improvements need on the codes please.
