parse command output in variable with loop

[dragrid]

would like to read and parse certain fields from multiple lines ( say lines 5 and 9 and the first and sixth fields respectively)
from the variable of the file the command output created
tried this code below but having problems parsing out_ping

ip_array = ('192.168.1.1', '192.168.1.1', '124.128.x.x')
for i in ip_array:
    out_ping = os.popen('ping' + ' ' + i, 'r+').read()
    #sys.stdout.flush()
    print out_ping

out_text = ('out_ping',5,9, 'r')    
for line in out_text:
   z = line.split()
if line 5 z[0] == "Reply" and line 9 z[6] < 80ms:
        #sys.stdout.writelines(z[2] + reachable + "\n")
        print z[2] + reachable + "\n"  
else
print "congested"

Your first for loop appears to work OK. Then you create a tuple and iterate on it in another for loop. The first item in the tuple is the string object 'out_ping'. Look at this:

>>> 'out_ping'.split()
['out_ping']
>>>

The following if statement is indented incorrectly. It only checks the last iteration of the preceding for loop.

Look at the following and see if you can adapt it for your purpose:

import os

ip_array = ('192.168.1.1',)
ping_results = []
for ip in ip_array:
    f = os.popen('ping %s' % (ip), 'r+')
    out_ping = [item.strip() for item in f.readlines() if item.strip()]
    f.close()
    ping_results.append(out_ping)

for result in ping_results:
    chk1 = result[4]
    chk2 = int(''.join([s for s in result[8].split()[-1] if s.isdigit()]))
    if chk1.startswith("Reply") and chk2 < 80:
        print chk1
        print result[8]
