无法获取主机名和 IP 并输出到文件 Python3

Question

I am currently trying to write my first Python3 program. In my program I am calling upon socket to get the IP and Hostname and write it to a file using a function (See code below). However, whenever I call the function it never outputs the IP or Hostname to the file IP.txt, it only writes the except message.

def get_Host_name_IP(): 
    try:
        f = open("IP.txt","w+") 
        host_name = socket.gethostname() 
        host_ip = socket.gethostbyname(host_name) 
        f.write("Hostname :  ", host_name)
        f.write("IP : ", host_ip)

    except: 
        f.write("Unable to get Hostname and IP")

write() takes one argument (string), so you need to format your strings properly:

def get_Host_name_IP(): 
    try:
        f = open("IP.txt","w+") 
        host_name = socket.gethostname() 
        host_ip = socket.gethostbyname(host_name) 
        f.write(f"Hostname :  {host_name}\n")
        f.write(f"IP : {host_ip}")
    except: 
        f.write("Unable to get Hostname and IP")
