Introduction

In addition to socializing with pals, humans are addicted to their smartphones. We primarily communicate via social media, such as WhatsApp, Facebook, Telegram, Instagram, and many others. It’s always interesting to see how people start using technology on social media platforms. Especially because it is a very simple pattern to understand. Recently BOT concepts have been used for many purposes, and it touches upon Artificial Intelligence patterns; as many are started learning Data Science, I thought to share my experience with the BOT concept. So I preferred the Telegram app, as I discovered it has numerous advantages over other apps in terms of entertainment, professionalism, academics, and other areas. This article will show how to create a Telegram BOT using Python programming language. We will also see how to get the bot up and running on our machine.

What is a BOT?

BOT, or “bots,” are computer programs that automate tasks on the internet. They can be used for various purposes, from interacting with customer service to handling large amounts of data. Bots can be used to save time and increase efficiency, and they’re becoming more and more common on the internet. It can help to increase efficiency by performing specific tasks automatically. They can be used to perform simple or complex tasks, such as communicating with other bots, parsing and understanding data, or undertaking tasks on a user’s behalf. Bots can be used for various purposes, such as customer service, marketing, and even automating tasks in the workplace.

What is the Use of BOT?

As the internet has become more prevalent, so too has the use of bots. Bots are software programs that allow you to automate repetitive tasks on the internet. BOTs can be a great way to save time and money.

There are several reasons why you might want to use a bot. For example, you might use a bot to bulk-download files from the internet. Or you might use a bot to automate a task you frequently do on the internet.

What are the Different Formats of BOT?

There are different types of BOTs, each with its strengths and weaknesses.

Natural language processing (NLP) bots can understand and respond to human commands in natural language. As a result, they can be used for various tasks, such as customer service, data entry, and automated marketing.

Robo-advisors are computer programs that provide financial advice to individual investors. They use artificial intelligence (AI) to analyze historical stock data, investment returns, and other market factors to give personalized investment advice.

Chatbots are computer programs that can hold a conversation with a human user. They can be used for various tasks, such as customer service, data entry, and automated marketing.

Virtual assistants are computer programs that can perform various tasks, such as finding information, making reservations, and managing your calendar. They use artificial intelligence (AI) to understand and respond to human commands in natural language.

What are the Types of BOT?

There are a few different types of bots. The first type of bot is a chatbot. Chatbots are computer programs that you can talk to. They can help you with tasks like booking a hotel or ordering food.

The second type of bot is a machine learning bot. Machine learning bots are different from chatbots because they can learn independently. For example, they can know how to book hotels or order food.

The third type of bot is a customer service bot. The term “customer service bot” has a few different meanings. Sometimes, a customer service bot is a software application that provides customer service support. These bots can answer questions, handle complaints, and help with customer service interactions.

Another meaning of a customer service bot is a chatbot that conversationally interacts with customers. These bots can provide customer service support, answer customer questions, and provide recommendations.

BOT vs. AI:

Bots are computer programs that automate customer service or content creation tasks. AI is a broader term that includes all the technologies used to create intelligent machines. Bots are a rapidly expanding field that combines artificial intelligence with computer programming to create compelling customer service, content creation, and much more. They can do things humans can’t, like understanding language, recognizing images, and more. Many companies are creating bots and platforms where people can interact with bots. Platforms such as Amazon Alexa or Apple Siri enable users to execute commands by talking to a bot.

Advantages & Disadvantages of BOT:

There are many advantages to using BOT technology in a business. One of the most important advantages is that BOT technology can help you automate tasks that human employees traditionally carry out. This can save you a lot of time and money. BOT technology can also help you to improve your business efficiency by carrying out repetitive tasks automatically. It can also help you to improve your customer service by handling customer inquiries automatically.

One of the disadvantages of BOTs is that they are not as autonomous as human beings. They cannot make independent decisions and can be controlled by their creators. This makes them vulnerable to being used for malicious purposes. Additionally, BOTs are not as effective as human beings at processing information and are, therefore, not as efficient at carrying out tasks.

What is the need for Telegram B?

Telegram is a messaging app with a focus on security and speed. It’s free, secure, and easy to use. You can send and receive messages, photos, and videos from anyone worldwide. Telegram also offers a range of features not available in other messaging apps, like group chats, stickers, and voice calls. Telegram is available on various devices, including PCs, smartphones, and tablets. It has a unique approach to communication that allows you to send and receive messages without opening a separate app. In addition, telegram is a bot platform that makes it easy to create and manage bots.

Telegram BOT is a new way to communicate with your friends and family. Telegram BOT can send and receive messages, photos, videos, and stickers. You can also use Telegram BOT to find information and make requests.

How to Create Telegram BOT using Python?

Creating Telegram BOT, consists of two main steps,

1. Getting Tokens and creating a BOT user from the Telegram app

2. Synchronizing and adding functionalities with Python code

So in the following, we can see about these two steps more elaborately,

1. Getting Tokens and creating a BOT user from the Telegram app

One of the main advantages of Python programming language is the library; with the help of a third-party library, we can make wonders. Here for creating Telegram BOT, we are using some basic libraries,

Step 1: Installing libraries,

Open Anaconda Prompt or command prompt and then install this pre-request library for developing BOT in the Telegram application as shown in the picture,

!pip install python-telegram-bot
creating BOT user from Telegram B

Step 2: To get the API key for the BOT, we need to open the Telegram Desktop version or APP version, then search for ‘BotFather’ with the verified symbol as shown in the figure, then proceed with the START option in that BOT,

Step 3: Then you get multiple options, as shown in the picture below,

As our primary purpose of this project is to develop Telegram BOT, choose the option /newbot or type /newbot for further process.

Step 4: Creating Telegram BOT and getting TOKEN from Telegram App,

After we type /newbot, it will ask for the username for the BOT. First, we need to give as per the application or website based or anything, as shown in the picture, then we need to create the bot name with either the title should have xxxxBOT or xxx_bot in. Either way, we can give. It can be any combination of alphabet or numerals with special characters.

Now we successfully created the link and username of Telegram BOT; also, we got the token API for creating BOT, as shown in the picture.

Step 5 for privacy setup in Telegram: We need to set the privacy, which means apart from us, no other person can use the API key, so we need to DISABLE the process so that we can be the sole authority for this BOT; others cannot be able to do any alteration or hacking kind of thing,

With this, we finished the Telegram side process and proceeded with Python.

2. Synchronizing and adding functionalities with Python code

Importing basic libraries,

from telegram.ext.updater import Updater
from telegram.update import Update
from telegram.ext.callbackcontext import CallbackContext
from telegram.ext.commandhandler import CommandHandler
from telegram.ext.messagehandler import MessageHandler
from telegram.ext.filters import Filters

The next step is to set the API key for creating and updating the functionalities,

#initialize API token - Telegram
telegram_token = 'API Key paste it here
#creating objects to perform a task
updater = Updater('API key paste it here, use_context=True)
dispatcher = updater.dispatcher

The next step is to create the functionalities that we need to display in the Telegram BOT,

#creating functionalities 
def start(update, context):
  update.message.reply_text('Hello! Welcome to anandsdata BOT! Enjoy the resource!')    
  update.message.reply_text('Type /help for the content to display!')
  update.message.reply_text('Happy Learning!')
def help(update, context):
  update.message.reply_text(
      """
      /start -> Welcome to the anandsdata BOT!
      /help -> This particular message
      /Python_udemy1 -> Python weblink with certification by Kirill Eremenko
      /Python_udemy2 -> Python and projects, weblink with certification by Dr Angelina
      /Python_YT -> Python weblink youtube by Dr Chunk
      /Python_series -> My YouTube channel about Python series
      /Python_blog -> Python Blog material
      /DataScience_blog -> Data Science blog material
      /analytics_blog -> Blogs wrt data science in Analytics Vidya
      /Scribbling_blog -> Scribbling blog material
      /github_repo -> Github repository
      /SQL -> materials for SQL
      /contact -> contact information
      """)

The next step is to give the links or other information that is correlated with the above options,

def Python_udemy1(update, context):
  update.message.reply_text('Udemy link: https://www.udemy.com/course/machinelearning/')
def Python_udemy2(update, context):
  update.message.reply_text('Udemy link: https://www.udemy.com/course/100-days-of-code/')
def Python_YT(update, context):
  update.message.reply_text('YouTube link: https://www.youtube.com/watch?v=8DvywoWv6fI&t=21928s')
def Python_series(update, context):
  update.message.reply_text('YouTube link: https://www.youtube.com/playlist?list=PL_MPYn9hN7UrS5bfykD5yba-HSdHEfWsn')
def Python_blog(update, context):
  update.message.reply_text('My blog link: https://www.anandsdata.com/blog/categories/python')
def DataScience_blog(update, context):
  update.message.reply_text('My blog link: https://www.anandsdata.com/blog/categories/data-science')
def analytics_blog(update, context):
  update.message.reply_text('My Analytics Vidya link: https://www.analyticsvidhya.com/blog/author/premanand17/')
def Scribbling_blog(update, context):
  update.message.reply_text('My Scribblings or thoughts in TAMIL link: https://www.anandsdata.com/blog/categories/snippet')
def github_repo(update, context):
  update.message.reply_text('My GitHub repository link: https://github.com/anandprems?tab=repositories')
def SQL(update, context):
  update.message.reply_text('YouTube link: https://www.youtube.com/watch?v=HXV3zeQKqGY')
def contact(update, context):
  update.message.reply_text('Blog link: https://linktr.ee/anandsdata')

Lastly, we need to update the functionalities with the commands we need to give it in BOT,

dispatcher = updater.dispatcher
updater.dispatcher.add_handler(CommandHandler('start', start))
updater.dispatcher.add_handler(CommandHandler('help', help))
updater.dispatcher.add_handler(CommandHandler('Python_udemy1', Python_udemy1))
updater.dispatcher.add_handler(CommandHandler('Python_udemy2', Python_udemy2))
updater.dispatcher.add_handler(CommandHandler('Python_YT',Python_YT))
updater.dispatcher.add_handler(CommandHandler('Python_series',Python_series))
updater.dispatcher.add_handler(CommandHandler('Python_blog',Python_blog))
updater.dispatcher.add_handler(CommandHandler('DataScience_blog',DataScience_blog))
updater.dispatcher.add_handler(CommandHandler('analytics_blog',analytics_blog))
updater.dispatcher.add_handler(CommandHandler('Scribbling_blog',Scribbling_blog))  
updater.dispatcher.add_handler(CommandHandler('github_repo',github_repo))  
updater.dispatcher.add_handler(CommandHandler('SQL',SQL))
updater.dispatcher.add_handler(CommandHandler('contact',contact))
updater.start_polling()  # Start the bot
updater.idle() # Wait for the script to be stopped; this will stop the bot

Finally, the Telegram BOT looks like this,
