Python 为什么我的代码不工作AttributeError:'；int'；对象没有属性'；isdigit'； #猜猜数字 随机输入 def是有效的数值（数值）： 如果num.isdigit（）和1

isdigit（）

是一个字符串方法，那么它对

int

输入不起作用

更改此项：

guess=int（输入（'enteranum'））

为此：

guess=input（'enteranum'）

编辑后的代码：

#猜猜数字
随机输入
def是有效的数值（数值）：
如果num.isdigit（）和1
isdigit（）
是字符串上的方法。您已经将
num
转换为整数，方法是在
input（）
调用周围添加
int（）
。您执行了吗？我已经编辑了答案以包含您的完整代码，请尝试并告诉我这是否是您正在寻找的结果
#Guess the num
import random
def is_valid_num(num):
    if num.isdigit() and 1 <= int(num) <= 100:
        return True
    else:
        return False

def main():
    number = random.randint(1,100)
    guessed_number = False
    guess = input('enter a num')
    #guess = (input('enter a num'))
    num_of_guesses = 0
    while not guessed_number:
        if not is_valid_num(guess):
            #return False
            guess = input('i count only digits enter 1<num<100')
            continue
        else:
            num_of_guesses += 1
            #break
            guess = int(guess)
        if guess < number:
            print ('entered number is low')

        elif guess > number:
            print ('entered number is high')

        else:
            print ('you got in',num_of_guesses, 'guesses')
            guessed_number = True
main()

@Thanks Issac Full code is below

#Guess the num
import random
def is_valid_num(num):
    if num.isdigit() and 1 <= int(num) <= 100:
        return True
    else:
        return False

def main():
    number = random.randint(1,100)
    guessed_number = False
    guess = input('enter a num')
    #guess = (input('enter a num'))
    num_of_guesses = 0
    while not guessed_number:
        if not is_valid_num(guess):
            #return False
            guess = input('i count only digits enter 1<num<100')
            continue
        else:
            num_of_guesses += 1
            #break

            guess = int(guess)
        if guess < number:
            guess = (input('entered number is low try again'))
        elif guess > number:
            guess = (input('entered number is high try again'))
        else:
            print ('you got in',num_of_guesses, 'guesses')
            guessed_number = True
main()
