• VPS / VDS servers
• Preconfigured operating system
• Own telegram bot server on Debian 12
• Chatbot ready-made answers for telegrams in Python

To test the performance of a Python chat bot, we used ready-made questions and answers preconfigured telegram bot server. This bot can answer pre-prepared questions - pre-prepared answers that are contained in the answers.txt file, as well as keep a log.

Let's proceed with the installation:

source my-tel-bot/bin/activate
pip install fuzzywuzzy
pip install python-Levenshtein

mkdir /root/my-tel-bot/data
chmod 775 /root/my-tel-bot/data

Let's prepare a file with questions and answers:

nano /root/my-tel-bot/data/answers.txt

u: hello
Welcome to the chatbot
u: what is your name
Bro Bot!
u: how old are you
relatively few
u: what can you do
You can add to my database in the answers.txt file

Let's replace our demo bot with the existing one:

/root/my-tel-bot/bot.py

import telebot
import os
from fuzzywuzzy import fuzz

# Create a bot, write your own token
bot = telebot.TeleBot('
Key received from @BotFather
')

# Loading a list of phrases and answers into an array
mas=[]
if os.path.exists('data/answers.txt'):
    f=open('data/answers.txt', 'r', encoding='UTF-8')
    for x in f:
        if(len(x.strip()) > 2):
            mas.append(x.strip().lower())
    f.close()

# Using fuzzywuzzy, we calculate the most similar phrase and give the next element of the list as an answer
def answer(text):
    try:
        text=text.lower().strip()
        if os.path.exists('data/answers.txt'):
            a = 0
            n = 0
            nn = 0
            for q in mas:
                if('u: ' in q):

                    # Using fuzzywuzzy we get how similar two strings are
                    aa=(fuzz.token_sort_ratio(q.replace('u: ',''), text))
                    if(aa > a and aa!= a):
                        a = aa
                        nn = n
                n = n + 1
            s = mas[nn + 1]
            return s
        else:
            return 'Error'
    except:
        return 'Error'

# /Start Command
@bot.message_handler(commands=["start"])
def start(m, res=False):
        bot.send_message(m.chat.id, 'I am in touch. Write me hello )')

# Receiving messages from a user
@bot.message_handler(content_types=["text"])
def handle_text(message):

    # Logging
    f=open('data/' + str(message.chat.id) + '_log.txt', 'a', encoding='UTF-8')
    s=answer(message.text)
    f.write('u: ' + message.text + '\n' + s +'\n')
    f.close()

    # Sending a response
    bot.send_message(message.chat.id, s)

# Launching the bot
bot.polling(none_stop=True, interval=0)

Done, don't forget to specify your key token in the script and restart the service:

service my-tel-bot restart
