Advice on efficiency. Python

I just finished a number guessing game similar to the video. It works but, I was just wondering if any of you professional programs have any advice for me. Something I could have or should have done differently or better?

Thanks.

EDIT

I added a try: to catch the ValueError if someone tried to guess with a letter or something silly.

import random
import numbers

guess_count = 0
guess = 8888
answer = 9999
finished = 0
game = "y"

while True:
    print("Number Guessing Game")
    game = input("Would you like to play? y or n? >> ")
    if game == "y":
        finished = 0
        answer = random.randint(1,10)

        while (finished == 0) and (guess_count <= 5):
            guess = int(input("Guess a whole number between 1 and 10 > "))

            if (guess >= 1) and (guess <= 10) and (finished != 1):

                if guess == answer:
                    print("That was the right answer!")
                    finished = 1

                elif guess_count == 4:
                    print("You ran out of guesses!")
                    break

                elif guess < answer:
                    print("That guess is too low")
                    guess_count += 1

                elif guess > answer:
                    print("That guess is too high")
                    guess_count += 1

            else:
                print("That is not a number between 1 and 10")
                break


    else:
        break

print("Goodbye!")

I found two bugs and have two suggestions:

  • you need to reset guess_count at game start :beetle:
  • bad inputs still break it (and I didn't see any "try" in the code) :beetle:
  • you don't need to check if "finished != 1" since the loop checks that it is 0
  • you could eliminate finished completely and just break on a right answer
