[Tutor] submitting batch jobs with python

[Isaac Hall]

Hi Bob,
Thank you, and one quick follow up question if I may.
If I did something like this,

commands=[<list of commandlines to send>]
output=[]
for i in range(len(commands)):
	a=os.popen(command[i]).readlines
	output.append(a)

where it takes the system a second or two to respond with the lines it
gives, would each iteration of the loop occur two seconds apart, or would
the loop keep going while a popen().readlines() waited for the system
response?
