The subprocess module is what you're looking for.
Your example would look like
--------------------%<--------------------
import subprocess
p = subprocess.Popen('cat hi.txt', shell=True, stdout=subprocess.PIPE)
for line in p.stdout:
print line
--------------------%<--------------------
I assume you know that you can just open a file for reading instead of
piping cat.
