I've done this in the past with the great help of nmap:

# nmap -sP 192.168.0.0/23

this will find hosts "alive" from 192.168.0.1 to 192.168.1.254

 From python, you can use it by saving it's output to a file and then 
reading or with the help of os.popen.


In this case, "alive" means that the hosts with the ip being analyzed 
responds to ARPs. see the manpage for nmap.
