'>'我猜数字游戏中'str'和'int'实例之间不支持 [英] '>' not supported between instances of 'str' and 'int' in my guess the number game

问题描述

我猜数字程序给我错误: main 中第26行的'str'和'int'实例之间不支持'>'.如果有人帮助我，我将不胜感激，谢谢.

In my guess the number program it gives me the error: '>' not supported between instances of 'str' and 'int' on line 26 in main. I would be grateful if someone helped me with this, Thank you.

import random
guesses = 0


def higher(guesses):
    print("Lower")
    gueeses += 1


def lower(guesses):
    print("Higher")
    guesses += 1


def correct(guesses):
    print("You got it correct!")
    print("It was {0}".format(number))
    guesses += 1


def _main_(guesses):
    print("Welcome to guess the number")
    number = random.randint(1, 100)
    while True:
        guess = input("Guess a number: ")
        if guess > number:
            lower(guesses)
        elif guess < number:
            higher(guesses)
        elif guess == number:
            correct(guesses)
            while True:
                answer = input("Would you like to play again? Y or N: ")
                if answer == "Y":
                    break
                elif answer == "N":
                    exit()
                else:
                    exit()


_main_(guesses)

推荐答案

默认情况下，input返回一个字符串.您需要将输入转换为数字类型，在这种情况下为整数.

By default, input returns a string. You need to convert your input to a numeric type, in this case integer.

替换:

guess = input("Guess a number: ")

使用:

guess = int(input("Guess a number: "))

您可能还希望验证用户输入，以确保实际上已为您提供了有效的整数.为此，您应该看到向用户询问输入直到他们给出有效的答复.

You may also wish to validate user input to ensure that you have actually been provided with a valid integer. For this you should see Asking the user for input until they give a valid response.
