Python:如何ping服务器？

import subprocess

def ping_server(server_ip):
    try:
        output = subprocess.check_output(['ping', '-c', '4', server_ip])
        return output.decode('utf-8')
    except subprocess.CalledProcessError as e:
        return e.output.decode('utf-8')

server_ip = '服务器IP地址'
result = ping_server(server_ip)
print(result)
