Question

下面是我的代码，用于生成0到9之间的随机数，并检查用户输入是否更高或更低。当我运行代码时，它没有输入并显示

'guessNumber = int（输入（“猜测0-9之间的随机数”）中的
错误）文件“”，第1行

有人可以告诉我我在哪里犯错误

#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()

我认为guessRandom()意味着在方法定义之外，以便调用方法。由于输入未分配为guessNumber，guessNumber变量永远不会更改，因此它会不断检查初始猜测。此外，小于/大于标志似乎与预期的消息冲突。此外，turn超出了方法的范围。

#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：假设您正在使用input in Python3（或在旧版本的Python中使用raw_input），除了ValueError之外，您可能需要输入字符串。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）。
