python - Shell script for a Git Repo -

i need create shell script (run.sh) file executes python code present in git repository , append repo. since first time, confused how create run.sh file , in language.

assuming output in stdout, might work:

#! /bin/bash  python main.py >> log git add log git commit -m 'update log' git push -u origin 

i have admit though, i'm not sure asking for. please clarify :)
