Hi there,
I'm struggling to find a sensible way to process a large chuck of
data--line by line, but also having the ability to move to subsequent
'next' lines within a for loop. I was hoping someone would be willing
to share some insights to help point me in the right direction. This
is not a file, so any file modules or methods available for files
parsing wouldn't apply.
I run a command on a remote host by using the pexpect (pxssh) module.
I get the result back which are pages and pages of pre-formatted text.
This is a pared down example (some will notice it's tivoli schedule
output).

I can iterate over each line by setting a for loop on the data object;
no problem. But basically my intension is to locate the line "Schedule
HOST" and progressively move on to the 'next' line, parsing out the
pieces I care about, until I then hit "Total", then I resume to the
start of the for loop which locates the next "Schedule HOST".
I realize this is a really basic problem, but I can't seem to
articulate my intension well enough to find documentation or examples
that have been helpful to me. I bought the Python cookbook yesterday
which has gotten me a lot further in some areas, but still hasn't
given me what I'm looking for. This is just a pet project to help me
reduce some of the tedious aspects of my daily tasks, so I've been
using this as means to discover Python. I appreciate any insights that
would help set me in the right direction.
Cheers,
-Rob
