3. #Subprocess
New in version 2.4.
The subprocess module allows you to spawn new processes, connect
to their input/output/error pipes, and obtain their return codes. This
module intends to replace several other, older modules and
functions, such as:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
