Variable is not defined error


The following script throws a "NameError: name 'guessed_number' is not defined " in line 21. But I don't understand why that would be the case.

Can anyone point me in the right direction?

Thanks. Vincent

import random

#generate a random number
random_number = random.randint(1, 10)

#Instruction of the game
print("You have to guess a number and have 3 tries")

#Ask for a number
def ask():
    guessed_number = int(input("What's your guess? "))

#innitial counter of tries 
tries = 0

while tries < 3:
     #Ask for a numbers
    #Compare random and guess number and show if low or high 
    if guessed_number == random_number:
        print("You won")
    elif guessed_number > random_number:
        print("Too high")
        tries =+1
        print("Too low")
        tries =+1

I believe the issue is that you're defining "guessed_number" in a function. When that happens, it stays inside that function and can only be used in that function. To fix this, you'll need to put at the very end of your function "return guessed_number". Then, replace "ask()" with "guessed_number = ask()". This will define "guessed_number" as what the ask() function defines it as.
