Python猜数字游戏：调用game函数无法重启游戏问题求助

问题根源 #

1. 全局变量状态残留：第一次游戏结束后，guesses_made已达到max_guesses（5次），再次调用game()时，while guesses_made < max_guesses条件不成立，循环直接跳过，导致游戏未启动。
2. 秘密数字未更新：重玩时仍使用第一次生成的secret_number，不符合游戏逻辑。
3. 输入处理冗余且不严谨：end()函数中重复的输入判断代码易出错，第二次输入未统一处理大小写。

修复后的代码 #

import random
import time

max_guesses = 5  # 固定参数可保留全局

def game():
    # 重置变量放在函数内部，避免全局状态残留
    secret_number = random.randint(1, 100)
    guesses_made = 0
    
    while guesses_made < max_guesses:
        guess = int(input("Enter your guess: "))
        guesses_made += 1

        if guess == secret_number:
            print("You guessed the correct number! You win!")
            break
        elif guess > secret_number:
            print("Your guess is too high. Try again.")
        elif guess < secret_number:
            print("Your guess is too low. Try again.")

        if guess != secret_number and guesses_made == max_guesses:
            print("You have run out of guesses. The secret number was", secret_number)
              
def end():
    while True:
        print("Play again?")
        user = input().casefold()
        
        if user == "yes":
            print("okay!")
            print()
            game()
        elif user == "no":
            print("okay, goodbye!")
            break
        else:
            print("That's not an option. Please say yes or no.")
            time.sleep(1)

# 初始引导内容
print("Hello player, let's play a guessing game.")
time.sleep(1.5)
print("I will pick a number between 1-100 and you have to try to guess it.")
time.sleep(1.5)

print()

print("I will give you five chances to guess the number. If you guess correctly I will give you a treat. If at the end you still cannot guess the number then I will tell you and we will play again.")
time.sleep(2)

print()

print("I hope you are ready!")
time.sleep(.5)
print("Ready...")
time.sleep(.25)
print("Set...")
time.sleep(.25)
print("GUESS!!!")
print()

game()
end()

关键修改点 #

• 将secret_number和guesses_made移至game()函数内部，每次调用都会重新生成秘密数字并重置猜测次数，彻底解决状态残留问题。
• 重构end()为循环结构，统一用casefold()处理输入大小写，避免重复代码，确保用户输入错误时持续提示直到输入有效选项。
• 移除不必要的全局变量，让函数逻辑更独立，减少全局状态引发的bug。
