Random.randit in python 3 [on hold]

I wanted to create a little game with the random.randit function. In this game, you have to guess a number (nombre_secret)with a number (nb) but when I run it i can't choose an answer. Can someone help me ?

import random

nombre_secret = random.randint(1,10)

nb = int (input("Guess the number:"))

while nb != nombre_secret:

if nb < nombre_secret:
    print: ("bigger!")

elif nb > nombre_secret:
    print: ("smaller!")

elif nb == nombre_secret:
    print: ("You Win!")
nb = input("try another one:")
