Python猜数字游戏如何处理非数字输入并输出无效提示

你的代码崩溃的核心原因是直接对用户输入做int()强制转换，当输入为非数字内容时会触发ValueError异常导致程序终止，同时原有代码还缺失random模块导入，运行时也会报错。

修改逻辑如下：

• 补充导入random模块
• 使用try-except块捕获输入转换时的ValueError异常，捕获到后输出要求的提示，且无效输入不计入猜测次数

import random
# 原代码导入的time模块未使用，不需要可直接删除

guesses_made = 0

name = input('Hello! What is your name?\n')

number = random.randint(1, 20)
print('Well, {0}, I am thinking of a number between 1 and 20.'.format(name))

while guesses_made < 5:
    guess_input = input('Take a guess: ')
    # 捕获非数字输入异常
    try:
        guess = int(guess_input)
    except ValueError:
        print('not a valid answer')
        continue
    
    guesses_made += 1

    if guess < number:
        print('Your guess is too low.')
    if guess > number:
        print('Your guess is too high.')
    if guess == number:
        break

if guess == number:
    print('Good job, {0}! You guessed my number in {1} guesses!'.format(name, guesses_made))
else:
    print('Nope. The number I was thinking of was {0}'.format(number))
