print socket.gethostname() >>Virtualbox123
The script below, will return the IP address of the hostname given. If it cannot find the hostname, it will print the error to screen using the exception handling "gaierror" (raised for address-related errors).
import socket name = "wwaxww.python.org" try: host = socket.gethostbyname(name) print host except socket.gaierror, err: print "cannot resolve hostname: ", name, err
If you look in the name, I misspelled the address to let you see how the error message would look like >>cannot resolve hostname: wwaxww.python.org [Errno -5] No address associated with hostname And if I run it again with the correct spelling
import socket name = "www.python.org" try: host = socket.gethostbyname(name) print host except socket.gaierror, err: print "cannot resolve hostname: ", name, err
