Rudiments of the same thing in Python (spacing and indents matter):

#!/usr/bin/env python
# Return IP Of Hostnames Specified On Commandline

from socket import gethostbyname
from sys    import argv

for host in argv[1:]:
    try:
        print gethostbyname(host), " " * 8, host

    except:
        print "Invalid Hostname: %s" % host
