shorten this to:

for cmd in commands:
         a=os.popen(cmd).readlines() # NOTE () after readlines!
         output.append(a)

then use list comprehension to shorten it to:

output = [os.popen(cmd).readlines() for cmd in commands]

>Would each iteration of the loop occur two seconds apart

Yes.

>the loop keep going while a popen().readlines() waited for the system 
>response?

To do that you'd need to use threads.
