Question

我为一个数字猜谜游戏编写代码，它必须通过递归出售。但是当我执行它时，我得到了这个错误：超出了最大递归深度。这是为什么？

这是我的代码：

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guess在您第一次调用函数时等于n，否则您将获得无限递归，因为您使用相同值{{game调用guess 1}}。您没有提供任何方法来停止递归。

Answer 2

您的游戏功能不需要任何参数。您需要使用else代替上一个elif并且guess = int(input("Introduce a number: "))步骤应该在您的游戏功能中（已测试）：

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

maximum recursion depth exceeded由于guess > n，guess < n条件满足时的无限循环而发生。要进一步了解this question。

以下代码应按预期工作。

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

您需要使用random.randint()这样的功能：n = random.randint(0, 100)。
建议使用while循环。
您没有再次致电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)

为什么我不断超出最大递归深度错误？
