Problem with Scapy ARP request in netscanner

Question

I was creating a netscanner using scapy, but i got an error...

When i put a normal ip address, the arp request arrive and return with no problem, but when i try to send it to all the ip in the network with ip/24 this error pop up!

Code:

import scapy.all as scapy
import sys

if len(sys.argv)==2:
    def scan(ip):
        arp_request = scapy.ARP(pdst = ip)
        arp_request.show()
        broadcast = scapy.Ether(dst="ff:ff:ff:ff:ff:ff")
        broadcast.show()
        arp_request_broadcast = broadcast/arp_request
        arp_request_broadcast.show()

    scan(sys.argv[1])

Error:

Traceback (most recent call last):
AttributeError: 'NoneType' object has no attribute 'split'

I've resolved it! The arp_request.show() and arp_request_broadcast.show() created the error. Simply remove them and it will work fine!
