How can I implement a start button in a Telegram bot using the Python Telegram Bot library?

I am looking to create a basic Telegram bot utilizing the Python Telegram Bot library. My goal is to present a ‘START’ button on the keyboard, allowing users to engage with the bot without needing to input the ‘/start’ command. What is the process to achieve this using the Python Telegram Bot library?

From personal experience with the Python Telegram Bot library, you can achieve a start button by customizing the ReplyKeyboardMarkup for your bot. This will enable users to initiate interaction with a simple button click rather than entering a command manually. First, create the keyboard with a button labeled ‘START’. You’ll need to instantiate the ReplyKeyboardMarkup class and pass in your keyboard layout as a list of lists, with each inner list representing a row of buttons. Then, within your handler function for the start command, simply include this markup when sending your reply. Make sure to add logic to handle the button press by checking the user’s response against the expected ‘START’ label.
