Sh (Subprocess) vs Os

os.py

import os

# Executed with output:
# Already on 'develop'
# Your branch is up-to-date with 'origin/develop'.
os.system('git --git-dir /tmp/app/.git --no-pager checkout -f develop')

# Git status returns:
# On branch develop
# Your branch is up-to-date with 'origin/develop'.
# nothing to commit, working directory clean

sh.py

from sh import git

# Steps 
# 1. Clone branch to folder
# 2. Switch branch


# Executed 2 times with output:
# Already on 'develop'
# Your branch is up-to-date with 'origin/develop'.
for line in git.checkout("-f", branch, _err_to_out=True, _iter=True):
  print(line)
  
# Git status returns:
# deleted:    docker-compose-dev.yml
# modified:   src/index.html
