Number Game

Given below is my version of code for this problem. I am unable to understand what is wrong with it. It throws an error saying local variable 'guess' referenced before assignment. Please help. Given below is my code.

import random

def play_game():
    secret_num = random.randint(1,10)
    count = 1

    while count < 4:
        try:
            guess = int(input("enter a number between 1 and 10 "))
            print(guess)
        except ValueError:
            print("{} is not a number".format(guess))
        else:
            if guess == secret_num:
                print("you've hit it! My number was {}".format(secret_num))
                break
            elif (secret_num - guess) >= 5:
                count += 1
                if count == 4:
                    print("Game Over! My number was {}".format(secret_num))
                    choice = input("To continue the game please type PLAY else type QUIT ")
                    if choice == "PLAY":
                        play_game()
                    else:
                        print("Thank you")
                else:
                    print("""too low.
                    Remaining chances:{}""".format(4-count))
            elif (guess - secret_num) >= 5:
                count +=1
                if count == 4:
                    print("Game Over! My number was {}".format(secret_num))
                    choice = input("To continue the game please type PLAY else type QUIT ")
                    if choice == "PLAY":
                        play_game()
                    else:
                        print("Thank you")

                else:
                    print("""too high
                    Remaining Chances:{}""".format(4-count))
            else:
                count += 1
                if count == 4:
                    print("Game Over! My number was {}".format(secret_num))
                    choice = input("To continue the game please type PLAY else type QUIT ")
                    if choice == "PLAY":
                        play_game()
                    else:
                        print("Thank You!")
                else:
                    print(
                    """almosth there!
                    Remaining Chances: {}""".format(4-count))
play_game()

The issues is in the try...except statement. If the guess can not be converted to an int then an error is raised before guess gets assigned. Use two statements to be sure guess gets a value:

        try:
            guess = input("enter a number between 1 and 10 ")
            guess = int(guess)
            print(guess)
        except ValueError:
            print("{} is not a number".format(guess))
        else:
            # ...
