Question

我刚刚编写了一个猜测随机数的快速脚本。虽然脚本'恭喜你赢了等'的最后一行没有运行。此外，在某些解释器中，它发出错误“无法运行脚本”。

Error in cat(name) : object 'name' not found
Error in own_brew(template, data[-1L]) :

我对您的脚本进行了一些修改。请注意，其功能受执行流程的约束，并且没有必要使用特殊控制语句（例如continue，break）或明确的干预来使其在逻辑上保持一致：

import random 


secret_number = random.randint(1, 100)
guess = None
attempts = 0

while secret_number != guess: 
    guess = int(input("Take a guess: ")) 
    attempts += 1

    if secret_number == guess:
        print("\nYou guessed it! The number was ", secret_number)
    elif guess < secret_number:
        print("Higher...")
    elif guess > secret_number:
        print("Lower...")

我改变了：

isCorrect变量。我删除它是因为它没有使用;
初始化guess变量的方式。在while语句之前是None;
while循环中的条件语句;
在while循环内从用户读取输入的顺序。

我建议直观地了解脚本的工作原理。

我尝试运行它并收到以下输出：

None@vacuum:~$ python3.6 ./test.py
Take a guess: 70
Higher...
Take a guess: 80
Higher...
Take a guess: 90
Higher...
Take a guess: 95
Lower...
Take a guess: 94
Lower...
Take a guess: 93
Lower...
Take a guess: 92
Lower...
Take a guess: 91

You guessed it! The number was  91

Answer 2

你应该从while循环中打印出这一行，因为当secret_number == guess时你的循环会中断。

while ...:
    if: 
        ... 
    elif: 
        ...

print "You guessed it! The number was {0}".format(secret_number)
