Nmap not found when run from Python script

Question

I have written basic port scanner for target ip and when I run it through kali vm it says sh: 1: nmap-F192.168.234.135: not found. but when I run nmap -F 192.168.234.135 ... its perfectly working. Can anyone point out the reason behind it. thanks

import os

def get_nmap(options,ip):
    command = "nmap" + options + "" + ip
    process = os.popen(command)
    result = str(process.read())
    return result

print(get_nmap('-F','192.168.234.135'))

Answer 1

Better, using the subprocess module:

def get_nmap(options, ip) :
    return subprocess.check_output(["nmap", options, ip])
#end get_nmap
