Python 2 - How to make the script go to a specific line?

This is kind of an extension to my last question, but I was wondering if it is possible to make the script go back to a specific line, if an event happens.

print "Type in 'Hello'"
typed = raw_input("> ")
if typed.lower() in ['hello', 'hi']:
    print "Working"
else:
    print "not working"

On the last line, if 'else' happens, can you make it so it restarts from line 2 again? Any help will be very greatly appreciated, thanks a lot!

there is 2 ways to do it , one with while loop , and one with recursion the two answer before mine solved your problem with while loop , so i'd solve yours with recursion 

def Inp():
    print "Type in 'Hello'"
    typed = raw_input("> ")
    if typed.lower() in ['hello', 'hi']:
       print "Working"
    else:
      print "not working"
      Inp()
Inp()

at the end just call the function Inp and it will continue asking for entering the value you want

You could put your code in an endless loop that only exits if the right word is typed in:

print "Type in 'Hello'"
while True:
    typed = raw_input("> ")
    if typed.lower() in ['hello', 'hi']:
        print "Working"
        break
    else:
        print "not working"

You can let the program lie in a loop till the correct input is given

while True: 
    print "Type in 'Hello'"
    typed = raw_input("> ")
    if typed.lower() in ['hello', 'hi']:
        break
