[Tutor] subprocess.Popen basics

[Todd]

Centos has SELinux enabled by default.  I dont know if SELinux is causing
your problem, but it is always worth looking at.

SELinux can keep a process from accessing files or executing another
process.

Try temporarily disabling  SELinux by running setenforce=0 as root.  Then
see if python does what you expect.
