LeBotTel 0.4.1

No project description provided

Abstract

LeBotTel is an easy to use python package to create your own Telegram bots for different use cases. For details how to use this package refer to the quick start section.

Name

The name LeBotTel is combined from "LeCun", "RoBot" and "Telegram". The "Le" in the name comes from Yann LeCun, to honor his work on neural networks (has nothing to do with this project, but he is a great scientist and pioneer in the field of neural networks (LeNet)). What has this bot to do with neural networks? We want to use this bot to log the training of neural networks. "Bot" comes from RoBot, because this is what the goal of this project is. And "Tel" comes from Telegram, because its a bot for Telegram. The "Pi" in our logo represents looks similar to the "tT" in "LeBotTel" and stands for the used Programming Language Python.

Quick Start

Installation

pip install LeBotTel

Send a message

from LeBotTel import BaseTelegramBot

bot = BaseTelegramBot(token="YOUR_BOT_TOKEN", chat_id="YOUR_CHAT_ID")

bot.send_message("Hello World!") # Raises ChatIdError if chat_id is not set

Hint: To get the chat_id you first have to send your Bot a message (e.g. /start). Then you need to send a GET request to the following URL:

https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates

In the returned JSON you will find the chat_id under message->chat->id.

Send an image

from LeBotTel.base_telegram_bot import BaseTelegramBot
import imageio
import io

bot = BaseTelegramBot(token="YOUR_BOT_TOKEN", chat_id="YOUR_CHAT_ID")

buffer = io.BytesIO()
img = imageio.imread('PATH_TO_IMAGE') # Image has to be in *.png format
imageio.imsave(buffer, img, format="PNG")

bot.send_image(buffer.getvalue()) # Raises ChatIdError if chat_id is not set

Send a gif

from LeBotTel.base_telegram_bot import BaseTelegramBot
import imageio
import io
import glob

bot = BaseTelegramBot(token="YOUR_BOT_TOKEN", chat_id="YOUR_CHAT_ID")

buffer = io.BytesIO()
images = []
image_files = glob.glob('PATH_TO_IMAGES_DIR/*.png') # Images have to be in *.png format

for image_file in image_files:
    images.append(imageio.imread(image_file))

imageio.mimsave(buffer, images, format="GIF", duration=30)

bot.send_gif(buffer.getvalue()) # Raises ChatIdError if chat_id is not set
