Question

我正在尝试做一个数字猜谜游戏，规则是您要获得10个猜谜才能找到随机生成的数字。它将显示您的猜测是否太高/太低，如果正确，程序将结束。但是由于某种原因，即使我猜错了，程序也结束了。如果有人可以解决我的问题，将不胜感激。

Actions ac= new Actions(driver);
ac.DragAndDrop(source, destination).Build().Perform();

Answer 1

break将直接退出循环

import random  


rand = random.randint(1,100)  
guesses = 0  

for i in range(10):  
    guess = int(input("Guess the secret number"))  
    if guess > rand:  
        print("your guess is too high")  
        guesses += 1  
        print("number of guesses",guesses,"/10")  
    if guess < rand:  
        print("your guess is too low")  
        guesses +=1  
        print("number of guesses",guesses,"/10")  
    if guess == rand:  
        print("you won")
        break # <- move break under the correct if statement

Answer 2

break语句用于终止当前循环。因此，当您使用它时，它将结束当前循环，并将控件传递给循环之后的语句。

在您的情况下，由于您已将break语句放在for循环的末尾，因此该循环在第一次迭代中终止。

因此，您所能做的就是将break语句放在最后一个if条件内，如下所示

import random  


rand = random.randint(1,100)  
guesses = 0  

for i in range(10):  
    guess = int(input("Guess the secret number"))  
    if guess > rand:  
        print("your guess is too high")  
        guesses += 1  
        print("number of guesses",guesses,"/10")  
    if guess < rand:  
        print("your guess is too low")  
        guesses +=1  
        print("number of guesses",guesses,"/10")  
    if guess == rand:  
        print("you won")  
        break

对于循环，在达到条件之前结束
