如何获取连接到Internet的适配器的IP和MAC地址？

import socket
import subprocess

# 获取本机IP地址
def get_ip_address():
    hostname = socket.gethostname()
    ip_address = socket.gethostbyname(hostname)
    return ip_address

# 获取本机MAC地址
def get_mac_address():
    try:
        output = subprocess.check_output(['ipconfig', '/all'], universal_newlines=True)
        for line in output.splitlines():
            if 'Physical Address' in line:
                mac_address = line.split(':')[1].strip()
                return mac_address
    except subprocess.CalledProcessError:
        return None

# 调用函数获取IP和MAC地址
ip_address = get_ip_address()
mac_address = get_mac_address()

print("IP地址:", ip_address)
print("MAC地址:", mac_address)
