Display addresses assigned to network interfaces using Python script.

Create a Python script using psutil package to extract system information and rich to pretty-print results.

#!/usr/bin/env python3
# Display IP addresses

import socket
import psutil

from rich import print

net_if_stats = psutil.net_if_stats()

previous_interface = ""

for interface, snicaddrs in psutil.net_if_addrs().items():
    for snicaddr in snicaddrs:
        if snicaddr.family in [socket.AF_INET, socket.AF_INET6]:
            if(previous_interface != interface):
                if net_if_stats[interface].isup == True:
                    interface_color = "green"
                else:
                    interface_color = "red"
                print()
                print("[bold %s]%s" % (interface_color, interface))
            print("  [italic white]%-8s [deep_sky_blue1]%s\n           [deep_sky_blue4]%s" % (str(snicaddr.family).split(';.';)[-1], snicaddr.address, snicaddr.netmask))
            previous_interface = interface
