Network help

[tondeuse34]

Hey guys, recently i started with socket programming in python and still doing it. And i decided to do a project, its a text based GUI with different options that are related to Networks, but ive had trouble with it looping back to the menu which the input is represented by ">>>" thats what i want to loop it back to. I'm thinking using a while loop to loop it back but when i tried it. The one option would just loop in a continuous loop. Any suggestions? Thanks

import socket, sys, urllib, urllib2, webbrowser

a = 0

print "Welcome!"

print "\nType 'help' or '/help' for a list of syntax commands"

command = raw_input("\n>>>")

if command == 'ip':
    host = raw_input("Host name: ")
    result = socket.gethostbyaddr("host")
    print "Primary hostname:"
    print "  " + result[0]

    print "\nAddresses:"
    for item in result[2]:
        print "  " + item
        print "\nDone"

elif command == 'web':
        print "\nCreating socket for connection..."
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

        s.connect(("www.google.com", 80))
        
        url = 'http://www.google.com'

        webbrowser.open_new_tab(url + '/doc')

        webbrowser.open_new(url)
        print "\nComplete"

elif command == 'html':
    link = raw_input("Type the desired website for page source: ")

    def addGETdata(url, data):
        return url + '?' + urllib.urlencode(data)

zipcode = 'S2S 7U8'
url = addGETdata('link',
                 [('query', zipcode)])
print "Using URL", url
req = urllib2.Request(url)
fd = urllib2.urlopen(req)
while 1:
    data = fd.read(1024)
    if not len(data):
        break
    sys.stdout.write(data)

if command == 'ip list':
    hostlookup = raw_input("Host name for matches: ")
    result = socket.getaddrinfo('hostlookup', None, 0, socket.SOCK_STREAM)

counter = 0
for item in result:
    print "%-2d: %s" % (counter, item[4])
    counter += 1

if command == 'socketpeer':
    print "Creating socket...",
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "done."

print "Looking up port number...",
port = socket.getservbyname('http', 'tcp')
print "done."

print "Connecting to remote host on port %d..." % port,
s.connect(("www.java2s.com", port))
print "done."

print "Connected from", s.getsockname()
print "Connected to", s.getpeername()

Yes, the standard way of writing a shell (which is what you are doing) is like this:

while True:
    inputline = raw_input(myprompt)
    parse inputline into command, operands
    if command == "quit": 
        break
    else:
        execute command using operands
