How to repeat a section of the program until the input is correct?

Question

I want my code to be repeated until the player guesses correctly.

ghuess=input("state a number between 1-100")
if ghuess>number:
    print "         


        

Answer 1

This is normally approached with a while loop:

while True:
    ... # do your thing
    if finished: # are we done here?
        break # leave
... # execution resumes here after break

Answer 2

For a solution without a break:

isFound = False
while not isFound:
    ghuess=input("state a number between 1-100")
    if ghuess>number:
        print "too high try again!"
    elif ghuess<number:
       print "too low try again!"
    else:
        isFound = True
        print "well done! ghuess you have won.."
        time.sleep(1)
        print "3"
        time.sleep(1)
        print "2"
        time.sleep(1)
        print "1"
        time.sleep(1)
        print prize

Answer 3

Add a while-loop there. This means you're looping the question again infinitely until you've reached a satisfactory result.

while True:
    ghuess=input("state a number between 1-100")
    if ghuess>number:
        print "too high try again!"
    elif ghuess<number:
        print "too low try again!"
    else:
        # Jackpot, exit the loop.
        break
print "well done! ghuess you have won.."
time.sleep(1)
print "3"
time.sleep(1)
print "2"
time.sleep(1)
print "1"
time.sleep(1)
print prize
