Python gets all of the NIC IP, mask and broadcast address of the machine

Search a day, unexpectedly did not find a suitable code to obtain the machine all the network card IP, mask and broadcast address, most of the socket is used, but the socket is usually returned to the intranet address, or the public network address, can not find all addresses, really too worried Mulberry, Decide yourself to filter by ifconfig or Ipconfig's return information. This time the code mainly uses the regular expression and the Subprocess module, and in order to be compatible with all platforms (Win,linux and Mac), also uses the platform to judge the system type, does not say too many, the code is as follows:

Import Subprocessimport reimport platformdef find_all_ip (platform): Ipstr = ' ([0-9]{1,3}\.) {3} [0-9] {1,3} ' if platform = = "Darwin" or platform = = "Linux": ipconfig_process = subprocess. Popen ("Ifconfig", stdout=subprocess. PIPE) output = Ipconfig_process.stdout.read () Ip_pattern = Re.compile (' (inet%s) '% ipstr) if platfor m = = "Linux": Ip_pattern = Re.compile (' (inet addr:%s) '% ipstr) pattern = Re.compile (IPSTR) Iplis            t = [] for ipaddr in Re.finditer (Ip_pattern, str (output)): IP = Pattern.search (Ipaddr.group ()) If Ip.group ()! = "127.0.0.1": Iplist.append (Ip.group ()) return iplist elif platform = = "Windows ": Ipconfig_process = subprocess. Popen ("ipconfig", stdout=subprocess.

Popen ("Ifconfig", stdout=subprocess.

Join (Map (str, broadlist)) def find_all_broad (platform): Ipstr = ' ([0-9]{1,3}\.) {3} [0-9] {1,3} ' if platform = = "Darwin" or platform = = "Linux": ipconfig_process = subprocess.

Hope to help you:)
