How to repeat an action until it is completed in Python

Question

from random import randint
guessed = randint(0,2)
user_guess = input("What do you think the number I'm thinking of is?")

if user_guess == guessed:
    print("Correct!")
else:
    print("Incorrect!")

I'm looking for a way for the code to repeat or a way to print different messages until user_guess is the same as guessed.

If the person guesses incorrectly, I want to be able to tell them that, and then give them another chance.

Thanks, sorry for beginner question.

Use a while loop.

from random import randint
correct = False
while (not correct): 
     guessed = randint(0,2)
     user_guess = int(input("What do you think the number I'm thinking of is?"))
     if user_guess == guessed: 
          print("Correct!")
          correct = True
     else: 
          print("Incorrect!")

You have to convert input in int type. `user_guess = int(input("What do you think the number I'm thinking of is?"))` – r0xette Feb 06 '17 at 18:45
Thanks R0xette and Andrew, it's now working perfectly. – Xander Forrest Feb 06 '17 at 20:41

Stay in a while loop as long as the guess is wrong. You need the first guess to "prime" the loop.

# get the first user guess

while user_guess != guessed:
    print "Incorrect"
    # Get next user guess

Note that the code for "next user guess" will be very similar to "first user guess".
