猜猜随机数为什么我无法输入 - python答案

【问题标题】：Guess Random Number Why i m not able to enter input - python猜猜随机数为什么我无法输入 - python

【问题描述】：

以下是我的代码，用于生成 0 - 9 之间的随机数，并通过用户输入检查它是更高还是更低。当我运行代码时，它没有接受输入并显示

'guessNumber = int(input("Guess a Random number between 0-9")) 文件“”中的错误，第 1 行'

谁能告诉我哪里出错了

#Guess Random Number
#Generate a Random number between 0 to 9

 import random
 turn = 0

 def guessRandom():
    secretNumber = random.randint(0,9)
    guessNumber = int(input("Guess a Random number between 0-9"))
    while secretNumber != guessNumber:
       if(secretNumber > guessNumber):
          input("You have Guessed the number higher than secretNumber. Guess Again!")
          turn = turn + 1
       elif (secretNumber < guessNumber):
          input("You have guessed the number lower than secretNumber. Guess Again! ")
       turn = turn + 1
    if(secretNumber == guessNumber):
        print("you Have Guessed it Right!")

guessRandom()

请正确格式化您的代码
其实我格式化了..当我复制到这里时，它是这样的。是不是有什么逻辑错误？
正确格式化这里。你得到了什么错误？

我认为guessRandom() 应该在方法定义之外，以便调用该方法。 guessNumber 变量永远不会改变，因为输入未分配为guessNumber，因此它将不断检查初始猜测。此外，小于/大于符号似乎与预期消息冲突。此外，turn 不在该方法的范围内。

#Generate a Random number between 0 to 9

import random


def guessRandom():
    secretNumber = random.randint(0, 9)
    guessNumber = int(input("Guess a Random number between 0-9: "))

    i = 0
    while secretNumber != guessNumber:
        if secretNumber < guessNumber:
            print "You have guessed a number higher than secretNumber."
            i += 1
        elif secretNumber > guessNumber:
            print "You have guessed a number lower than secretNumber."
            i += 1
        else:
            print("you Have Guessed it Right!")

        guessNumber = int(input("Guess Again! "))

    return i

turn = 0
turn += guessRandom()

编辑：假设您使用input in Python3（或在旧版本的Python 中使用raw_input），您可能希望除了ValueError 以防有人输入字符串。例如，

#Generate a Random number between 0 to 9

import random


def guessRandom():
    secretNumber = random.randint(0, 9)
    guessNumber = input("Guess a Random number between 0-9: ")

    i = 0
    while True:
        try:
            guessNumber = int(guessNumber)
        except ValueError:
            pass
        else:
            if secretNumber < guessNumber:
                print "You have guessed a number higher than secretNumber."
                i += 1
            elif secretNumber > guessNumber:
                print "You have guessed a number lower than secretNumber."
                i += 1
            else:
                print("you Have Guessed it Right!")
                break

        guessNumber = input("Guess Again! ")
    return i

turn = 0
turn += guessRandom()

我将while 循环条件更改为True 并添加了一个中断，否则它将无限循环（将整数与字符串输入值进行比较）。
