猜猜游戏Bug？

Question

我将以下代码用Python编写为项目。我把计算机科学作为GCSE。我是新手，所以不知道如何修复这个bug。当我输入我的第一个猜测时，例如'5'，它会说太高。然后，一旦游戏完成，它会说答案是7.这是一个我一直试图解决但无法完成的错误。这是我使用的代码：

import random 
numberofGuesses = 0 
print ("I'm thinking of a number between 1 and 10. What is it? You have three guesses.") 

while numberofGuesses < 3: 
    numberofGuesses = numberofGuesses +1 
    randomNumber = (random.randint(1,10)) 
    userInput = 0
    userInput = input () 
    userInput = int(userInput) 
    if randomNumber > userInput: 
        print("Too Low! Try again")
    if randomNumber < userInput:
        print("Too High! Try Again")

if numberofGuesses == 3:
    print("Sorry! You lose. The correct number was:",randomNumber)

if randomNumber == userInput: 
    print("Well Done! Your guess was correct!")`

除了我提到的一个bug之外，这段代码完美无缺。

Answer 1

每次进行猜测时，您都会重新选择一个随机数。相反，我相信您希望程序首先选择一个数字，然后输入您的while循环。

randomNumber = (random.randint(1,10)) 

while numberofGuesses < 3: 

    numberofGuesses = numberofGuesses +1 

    userInput = 0

    userInput = input () 

    userInput = int(userInput) 

    if randomNumber > userInput: 

        print("Too Low! Try again")

    if randomNumber < userInput:

        print("Too High! Try Again")

Answer 2

除了在每次迭代中重置随机数之外还有另一个问题：

如果猜测正确，你不会停止循环。你应该在猜测评估之后增加猜测计数器，否则你将无法判断第三次尝试是否有人正确猜测：

import random 
numberofGuesses = 0 
randomNumber = (random.randint(1,10)) 
print("I'm thinking of a number between 1 and 10. What is it? You have three guesses.") 

while numberofGuesses < 3: 
    userInput = int(input()) 
    if randomNumber > userInput: 
        print("Too Low! Try again")
    elif randomNumber < userInput:
        print("Too High! Try Again")
    else: # Correct guess!
        break
    numberofGuesses = numberofGuesses +1 
else:  # Executed only if the while loop is not exited via "break"
    print("Sorry! You lose. The correct number was:",randomNumber)

if randomNumber == userInput: 
    print("Well Done! Your guess was correct!")

Answer 3

您正在将randomNumber设置为每个猜测的新随机数 - 因此，对于第一个答案，它可能是7，然后您进行猜测并将其更改为3.要解决此问题，请移动randomNumber = (random.randint(1,10))在你的while循环之外 - 做一次，而不是每次猜测一次。干杯，祝你学习愉快！
