You should not do in this way. First you need to call the external command with output captured, and then write the output you captured to a file:

import subprocess

ip2 = raw_input('Enter ip of target: ')
p = subprocess.Popen(["nmap", "-sP", ip2], stdout=subprocess.PIPE)
out, err = p.communicate()
with open('123.txt', 'w') as f:
    f.write(out)

Basic idea is right, but I think you want to use user input to execute a command consisting of `['nmap`, `'-sP'`, `'']`. – martineau Mar 19 '19 at 22:00
