# Demo of using the ls command in Python

import subprocess

proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
output = proc.stdout.read()
print output

# My terminal:
# > $ python ls-example.py
# > README.md
# > ls-example.py
# >

# This is the output this script returned. The folder contained README.md,
# ls-example.py and .gitignore file. It also contained a .git folder. I don't
# know what the extra blank one is between .git and .gitignore cause I added
# a sub folder "test" and I got that in the list when I ran this again.
