Simple bot with polling - TELEGRAM BOT

main.py

__author__ = "Vycktor Stark"
"""
This is a simple project to run a bot on the telegram via polling (webscraping) without using a module or lib
to start the code, after the download, just first insert your bot key to it and run as follows: `python3 main.py`

Note: I am aware that it is much more practical to use the / lib module to create the code faster,
but the goal of this snippet is to demonstrate an alternative for you to create the code your way
