Hi Chris, this is my code: #!/usr/bin/env python #Get the IP Address import sys, socket 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> ")) if mchoice == 2: filename = raw_input("Hello, 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") if 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") ===================================================================== now where it says Finsihed the operation i want it to show (another search /main menu/exit program) i know about the while loop , but forgive me i just don't have a clue how to use it for this situation. i don't want you to give me the code:) just the idea. i did read the section about the while loop but still i do not know how to use it in this situation. thanks. -- http://mail.python.org/mailman/listinfo/python-list
