How to simplify my basic python coding higher/lower game?


I'm a beginner at Python and I wanted to try out my own little project based off the things I've learnt. It's a higher/lower game where the user gets a starting number and then has to guess if the next number is higher or lower than the previous one. The range is only between 1-10 inclusive and for each consecutive correct guess, the user scores a point.

The code technically works which I'm pleased about, however I believe it's quite messy and could be done in a far simpler way. The code is quite clunky around where the user gets their answer right and moves on to the next question as I had to use global variables. I would highly appreciate if someone took the time to look over it and see how it could get simplified. Thank you :)

number_list = [1,2,3,4,5,6,7,8,9,10]
start_number = random.choice(number_list)
should_continue = True
move_on = False
end_game = False
score = 0


def deal():
    return random.choice(number_list)
def higher_lower():
    input("Is the next number 'higher' or 'lower': ")
    return
def question():
    global should_continue, move_on, score, end_game, choice
    while should_continue:      
        choice = deal()
        if next_answer == "higher" and choice > old_number:
            print(f"The new number is {choice}. Good job!\n")
            score += 1
            should_continue = False
            move_on = True
        elif next_answer == "lower" and choice < old_number:

Solution

  • As Timus said, code review is better for this kind of question. Anyway, here's my version.

    import random
    
    c_list = {'higher': 1 , 'lower': 0}
    
    def game():
        score = 0
        cur_num = random.randint(1,10)
        old_num = cur_num
        print("Your starting number is " + str(cur_num))
        
        while True:
            while cur_num == old_num:
                cur_num = random.randint(1,10)
            choice = input("Is the next number 'higher' or 'lower': ")
            if (cur_num > old_num) == c_list[choice]:
                print("Good job! The new number is " + str(cur_num))
                score += 1
                old_num = cur_num
            else:
                print("you lose! New number is " + str(cur_num))
                break
        
        return score
    
    print("Welcome to the Higher/Lower game!\n")
    print("The rules of the game are simple.")
    print("You start off with a number, and you have to guess if the next number is 'higher' or 'lower'.")
    print("You will need to reply back with either 'higher' or lower'.")
    print("The numbers are between 1-10 inclusive. For each correct answer, you get a point.")
    print("The goal is to get as many points as possible without getting a wrong answer. Good luck!\n")
    
    high_score = 0
    
    while True:
        cur_score = game()
        if cur_score > high_score:
            high_score = cur_score
        print("Your score is " + str(cur_score))
        inp = "o"
        while inp not in ['Y', 'y', 'N', 'n']:
            inp = input("Want to continue? (Y/N): ")
        if inp in ['N', 'n']:
            break
        else:
            print("Start of new game.")
    
    print("End of game. Your highest score is " + str(high_score))
