电报“猜测数字”机器人每次收到用户的新猜测时都会更改密码

Question

我正在做一个“猜数字”的电报机器人，它被认为是一个从0到100的整数。当用户试图猜测数字时，机器人应该给他们提示，显示他们的猜测是小于还是大于秘密数字。但每次收到用户的新猜测时，它似乎都会更改密码。

下面是完整的代码

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()

它还说，变量'a'，它是一个秘密数字的存储，在guess_number函数中是不可能实现的。我认为变量应该放在其他地方，但不知道具体放在哪里。

用于多次聊天

如果你想让它为多个用户工作，你需要一个数据库来存储每个聊天的号码。一本字典可以作为一个小例子很好地工作。

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")

一次聊天

如果你只需要这个机器人在一次聊天中工作，你可以选择使用一个全局变量来存储密码。然后使用global关键字在函数中对其进行访问。

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")

在任何一种情况下，当机器人关闭时，数字都会丢失。选择适合的和keep this in mind的
