run scapy from python script ..

it's because your file name is scapy.py. You import your own file, not scapy package. Rename your file.

okay thank u its working now ... but i have another issue i need to get all the mac address from the arp_scan() function ... and pass them to another to get the vendor for each mac this is my code ... :

#! /usr/bin/python
import urllib2
import json
import codecs

def arp_scan():

        from scapy.all import srp,Ether,ARP,conf
        conf.verb=0
        ans, unans = srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst="192.168.20.0/24"),timeout=2)
        for snd,rcv in ans:
                d = rcv.sprintf("%Ether.src%")
                print(d)
                
                
arp_scan()



#API base url,you can also use https if you need
url = "http://macvendors.co/api/"
#Mac address to lookup vendor from
mac_address =  arp_scan()

request = urllib2.Request(url+mac_address, headers={'User-Agent' : "API Browser"}) 
response = urllib2.urlopen( request )
#Fix: json object must be str, not 'bytes'
reader = codecs.getreader("utf-8")
obj = json.load(reader(response))

#Print company name
print (obj['result']['company']);

error :

Error:
Traceback (most recent call last):
  File "/tmp/ArpScanner/arp.py", line 26, in <module>
    request = urllib2.Request(url+mac_address, headers={'User-Agent' : "API Browser"})
TypeError: cannot concatenate 'str' and 'NoneType' objects

Your arp_scan function does not have a return statement, so it returns None by default. So that's what mac_address gets set to, and that causes the error. You need to return the string version of whatever MAC address you're looking for from the arp_scan function.

how ?

With a return statement:

def add_two(x):
    return x + 2

Output:
>>> y = add_two(3)
>>> y
5

I'm not sure exactly what should be returned out of your function, but you would use the return statement to do it. If this is new to you, you should check out the functions tutorial (link in my signature below).
