Yes, the  return code will be 0 for ping regardless of
responses, unless you make a syntax error in your command etc.
You need to get the output from the ping command into Python
for analysis, rather than its return code.

Maybe this interactive example can give you some hints...

>>> import os
>>> ip = raw_input('IP? ')
IP? <something>
>>> result = os.popen('ping %s' % ip).read()
>>> print result
<something>
>>> print "time-out" in result
True
