為什么我不斷出現最大遞歸深度超出錯誤？

Question

我正在為數字猜謎游戲編寫代碼，必須遞歸出售。 但是當我執行它時，我得到這個錯誤：超過最大遞歸深度。 這是為什么？

這是我的代碼：

import random
n = random.randrange(0,100)
guess = int(input("Introduce a number: "))
def game(guess):
    if guess == n:
        print("Your guess is correct.")
    elif guess > n:
        print("Your guess is too high")
        game(guess)
    elif guess < n:
        print("Your guess is too low")
        game(guess)
game(guess)

Answer 1

原因是，除非第一次調用guess等於n ，否則您將具有無限遞歸，因為您以相同的guess值調用game 。 您沒有提供任何方法來停止遞歸。

Answer 2

您的游戲功能不需要任何參數。 您需要使用else代替最后一個elif並且guess = int(input("Introduce a number: "))步驟應該在您的游戲函數中（已測試）：

import random
n = random.randrange(0,100)
def game():
    guess = int(input("Introduce a number: "))
    if guess == n:
        print("Your guess is correct.")
    elif guess > n:
        print("Your guess is too high")
        game()
    else:
        print("Your guess is too low")
        game()
game()

Answer 3

滿足guess > n ， guess < n條件時，由於無限循環而導致出現maximum recursion depth exceeded 。 要知道進一步請參考這個問題 。

下面的代碼應按預期工作。

import random,sys
n = random.randrange(0,100)

def game(guess):
    if guess == n:
        print("Your guess is correct.")
        sys.exit()
    elif guess > n:
        print("Your guess is too high")
    elif guess < n:
        print("Your guess is too low")

while True:
    guess = int(input("Introduce a number: "))
    game(guess)

Answer 4

1. 您需要使用如下所示的random.randint()函數： n = random.randint(0, 100) 。
2. 建議使用while循環。
3. 您沒有再次調用guess = int(input("Introduce a number: ")) 。

import random
n = random.randint(0, 100)
guess = int(input("Introduce a number: "))

def game(guess):
    while guess != n:
        if guess > n:
            print("Your guess is too high")
        elif guess < n:
            print("Your guess is too low")
        guess = int(input("Introduce a number: "))

    else:
        print("Your guess is correct.")

game(guess)
