Telegram 'guess the number' 男孩每次收到用户的新猜测时都会更改密码

Question

我正在制作一个 'guess the number' 电报机器人，它应该会给出 0 到 100 之间的整数。当用户尝试猜测数字时，机器人应该给他们提示，显示他们的猜测是否正确小于或大于秘密数字。但它似乎每次收到用户的新猜测时都会更改密码。

这是完整的代码

import random
import telebot
from telebot.types import Message
bot = telebot.TeleBot("-token-")


@bot.message_handler(commands = ('start'))
def guess_number():
   a = random.randint(0,100)
   a = guess_number.variable
def send_welcome(message):
   bot.send_message(message.chat.id, "you entered a guessing game, traveller. Guess a number from 0 to 100, or be eaten by a  dragon.")

@bot.message_handler(func=lambda message: True)
def checking(message):
    try: 
        user_message = int(message.text)
        if user_message > guess_number.variable:
            bot.send_message(message.chat.id, "your number is greater than mine")
        elif user_message < guess_number.variable:
            bot.send_message(message.chat.id, "your number is smaller than mine")
        else:
            bot.send_message(message.chat.id, "yep, that's the right number")
    except ValueError:
            bot.send_message(message.chat.id, "you must enter an integer")
bot.polling()

a = random.randint(0,100) a = guess_number.variable 它还说变量 'a'，这是秘密号码的存储，在 guess_number 函数中是遥不可及的。我认为变量应该放在其他地方，但不能找出确切位置。

多人聊天

如果您希望它适用于多个用户，您将需要某种数据库来存储每次聊天的号码。字典可以作为一个小例子。

numbers = dict()

@bot.message_handler(commands=('start'))
def guess_number(message):
    numbers[message.chat.id] = random.randint(0, 100)

@bot.message_handler(func=lambda message: True)
def checking(message):
    try:
        user_message = int(message.text)
        if user_message > numbers[message.chat.id]:
            bot.send_message(message.chat.id, "your number is greater than mine")
        elif user_message < numbers[message.chat.id]:
            bot.send_message(message.chat.id, "your number is smaller than mine")
        else:
            bot.send_message(message.chat.id, "yep, that's the right number")
    except ValueError:
        bot.send_message(message.chat.id, "you must enter an integer")
    except (TypeError, KeyError):
        bot.send_message(message.chat.id, "there's no number to guess! say /start to start")

单次聊天

如果您只需要此机器人进行一次聊天，您可以选择使用单个全局变量来存储密码。然后使用 global 关键字使其在函数内可访问。

the_number = None

@bot.message_handler(commands=('start'))
def guess_number(message):
    global the_number
    the_number = random.randint(0, 100)

@bot.message_handler(func=lambda message: True)
def checking(message):
    global the_number
    try:
        user_message = int(message.text)
        if user_message > the_number:
            bot.send_message(message.chat.id,"your number is greater than mine")
        elif user_message < the_number:
            bot.send_message(message.chat.id,"your number is smaller than mine")
        else:
            bot.send_message(message.chat.id, "yep, that's the right number")
    except ValueError:
        bot.send_message(message.chat.id, "you must enter an integer")

无论哪种情况，当机器人关闭时，号码都会丢失。选择合适的 keep this in mind
