【问题描述】：

import random
level = input("Easy gets 10 attempt Hard getse 5 attempt choose a level --> ").lower()
number = random.choice(range(101))
attempt = 0
if level == "easy":
    attempt = 10
else:
    attempt = 5

def check_number(guess,num):
    if guess == num:
        return "Correct You Won :)"
        win = True

    elif guess > num:
        return "Too high :("
    elif guess < num:
        return "Too low :("
win = False
while attempt > 0 and win == False:
    guess = int(input("Guess the number "))
    print(check_number(guess,number))
    attempt -= 1
    print(f"You have {attempt} attempt left")

if win == True:
    print(f"GOOD JOB YOU HAVE {attempt} LEFT")
else:
    print("NEXT TİME :(")

当你猜数字时它不会停止，仍然要求新的猜测。我找不到问题。我刚开始学习python。

【问题讨论】：

你函数中的win是一个局部变量，没有连接到win全局变量。当然，这没关系，因为在您返回之前，您不会将 win 设置为 True。我会在下面发布一个更好的设计。
不要使用globals，它们可能会导致更新变量时出错。

【解决方案1】：

这完全避免了使用全局变量：

import random
level = input("Easy gets 10 attempt Hard getse 5 attempt choose a level --> ").lower()
number = random.choice(range(101))
attempt = 0
if level == "easy":
    attempt = 10
else:
    attempt = 5

def check_number(guess,num):
    if guess > num:
        return False, "Too high :("
    elif guess < num:
        return False, "Too low :("
    return True, "Correct You Won :)"

win = False
while attempt > 0 and not win:
    guess = int(input("Guess the number "))
    win, msg = check_number(guess,number)
    print(msg)
    if not win:
        attempt -= 1
        print(f"You have {attempt} attempt left")

if win:
    print(f"GOOD JOB YOU HAVE {attempt} LEFT")
else:
    print("NEXT TİME :(")

【解决方案2】：

你的代码有两个问题：

win 返回后分配，不会运行
win 在函数内部，就像您在函数内部定义了一个新变量 win 并且无法从外部访问它

所以你可能想这样做：

import random
level = input("Easy gets 10 attempt Hard getse 5 attempt choose a level --> ").lower()
number = random.choice(range(101))
attempt = 0
if level == "easy":
    attempt = 10
else:
    attempt = 5

def check_number(guess,num):
    if guess == num:
        return 0
    elif guess > num:
        return 1
    elif guess < num:
        return -1
win = False
while attempt > 0 and win == False:
    guess = int(input("Guess the number "))
    state = check_number(guess,number)
    if(state==0):
        win = True
        print("won")
    elif(state==1):
        print("is high")
    elif(state==-1):
        print("is low")
    attempt -= 1
    print(f"You have {attempt} attempt left")

if win == True:
    print(f"GOOD JOB YOU HAVE {attempt} LEFT")
else:
    print("NEXT TİME :(")
