missing 1 required positional argument?

I cant get what is wrong with this code? It keeps giving me an error. I do not wanna create a class. It keeps giving me the "missing 1 required positional argument 'choice' in the main function. Anyone have any suggestions? The script is supposed to be a menu with all functions connected to the main. I tried to do elif's, hopefully it helps. I probably need to use "self"

import socket
import uuid
import os
import re

HNAME=1
IP=2
MAC=3
ARP=4
ROUT=5
QUIT=6

    print("_____________________________________")

    print("2. Display the IP Address")
    print("3. Display the MAC Address")
    print("4. Display the ARP Table")
    print("5. Display the Routing Table")
    print("6. Quit")
    print()
    
    choice = int(input("Enter your choice: "))
    print()
    return choice

def choicefun(choice):
   
    while choice > QUIT or choice < HNAME:
        
        choice = int(input("Please enter a valid number: "))
        print()
        
    return choice

def get_hostname(host):
    host=socket.gethostname()
    print("\n The host name is: ", host)
    #return host

def get_ipaddr(ipv4):
    ipv4=socket.gethostbyname()
    print("\n The IPv4 address of the system is: ", ipv4)
    #return ipv4

def get_mac(ele):
    print ("The MAC address is : ", end="") 
    print (':'.join(['{:02x}'.format((uuid.getnode() >> ele) & 0xff) 
    for ele in range(0,8*6,8)][::-1]))

def get_arp(line):
    print("ARP Table")
    with os.popen('arp -a') as f:
        data=f.read()
    for line in re.findall('([-.0-9]+)\s+([-0-9a-f]{17})\s+(\w+)',data):
        print(line)
    return line

def main(choice):
    counter=False
    while counter==False:
        get_user_choice()
        choicefun()
        if choice == 6:
            counter==True
        elif choice == 1:
            get_hostname()
        elif choice == 2:
            get_ipaddr()
        elif choice == 3:
           get_mac() 
        elif choice== 4:
            get_arp()
        elif choice == 5:
            __pyroute2_get_host_by_ip()

main()

This occurs because you are calling the main function without the corresponding choice argument:

def main(choice):
    ...
main()

You either need to pass a choice argument or remove the choice parameter from the function. It seems like choice is mainly defined by get_user_choice(), in which case the code could read:

def main():
    counter=False
    while counter==False:
        choice = get_user_choice()
...

However, the get_user_choice function also has a choice parameter. Since this argument is overridden with choice = int(input("Enter your choice: ")) you likely want to define the function as:

def get_user_choice():
    ...
