Finding local IP addresses using Python's stdlib

Here is a code snippet that uses the socket module from Python's standard library to find the local IP addresses of the host machine:

find the local IP addresses of the host machine using socket module

import socket

def get_local_ip():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    try:
        # 10.255.255.255 is a broadcast address that forces the OS to select the default route interface
        s.connect(('10.255.255.255', 1))
        IP = s.getsockname()[0]
    except Exception:
        IP = '127.0.0.1'
    finally:
        s.close()
    return IP

print(get_local_ip())

This code creates a socket and connects to a non-local address using the socket's connect method. Then it retrieves the socket's own address using getsockname() method, which returns a tuple containing the IP address and the port number.

Note that you may have multiple IP addresses. If you want to see all IP addresses, use socket.gethostbyname_ex(socket.gethostname())[2].
