hi,
found a solution,
it's not quite like Chris advised but it works.
#!/usr/bin/env python
#Get the IP Address
import sys, socket, os
def restart_program():
python = sys.executable
os.execl(python, python, * sys.argv)
print ("\n\n#########################################################")
print ("# Get IP from Host v 1.0 #")
print ("#########################################################")
print ("# Choose from the options below #")
print ("# 1- url , 2-File(Text file only.txt) #")
print ("#########################################################\n")
mchoice = int(raw_input("Please enter your choice> "))
while mchoice !=1 and mchoice !=2:
print("{0} is not a menu option.".format(mchoice))
mchoice = int(raw_input("Please try again> "))
while mchoice == 2:
filename = raw_input("Please enter file name here> ")
if filename.endswith(".txt"):
try:
infile = open(filename)
except EnvironmentError as e:
print(e)
sys.exit(1)
print("\nFile {0} exists!".format(filename))
print("\nGetting IP addresses for hosts")
print("\n")
else:
print("{0} is not a Text file.".format(filename))
sys.exit(1)
for line in infile:
hostname = line.strip()
try:
ip_address = socket.gethostbyname(hostname)
except EnvironmentError as e:
print("Couldn't find IP address for {0}: {1}".format(hostname, e))
continue
print("IP address for {0} is {1}.".format(hostname, ip_address))
else:
print ("\nFinished the operation")
print ("A=another search, M=main menu, E=exit")
waction=raw_input("Please choose your action > ")
while waction !='A' and waction !='M' and waction !='E':
print("{0} is not a valid action.".format(waction))
waction=raw_input("Please try again> ")
if waction =='E':
sys.exit(1)
if waction =='A':
continue
if waction =='M':
print ("#########################################################")
print ("# Choose from the options below #")
print ("# 1- url , 2-File(Text file only.txt) #")
print
("#########################################################\n")
mchoice = int(raw_input("Please enter your choice> "))
while mchoice !=1 and mchoice !=2:
print("{0} is not a menu option.".format(mchoice))
mchoice = int(raw_input("Please try again> "))
while mchoice == 1:
murl = raw_input("Enter URL here> ")
try:
print("Checking URL...")
ip_address = socket.gethostbyname(murl)
except EnvironmentError as d:
print(d)
sys.exit(1)
print("Valid URL")
print("\nIP address for {0} is {1}.".format(murl, ip_address))
print ("\nFinished the operation")
print ("A=another search, M=main menu, E=exit")
waction=raw_input("Please choose your action > ")
while waction !='A' and waction !='M' and waction !='E':
print("{0} is not a valid action.".format(waction))
waction=raw_input("Please try again> ")
if waction =='E':
sys.exit(1)
if waction =='A':
continue
if waction =='M':
restart_program()
