@bot.on_message(phrase="/start")
def command_start(message):
    btn = Button(text="What is your name", phrase="/name")
    bot.send_message(message.user.login, "Select an action", inline_keyboard=[btn])


@bot.on_message(phrase="/name")
def command_start(message):
    bot.send_message(message.user.login, "Type your name")
    bot.register_next_step_handler(message.user.login, type_your_name)


def type_your_name(message):
    bot.send_message(message.user.login, f"Your name is {message.text}")


bot.run()

Message processing

To process all messages starting with a specific phrase, use decorator @bot.on_message. Specify in the parameters phrase to handle messages that begin with the specified phrase.

phrase checks the first word of the text from the user

@bot.on_message(phrase="/start")
def command_start(message):
    bot.send_message(message.user.login, f"Hello, {message.user.login}")

To send a message use bot.send_message. You can provide chat_id or login there.

bot.send_message(message.user.login, "Hello, I'm bot")

inline_keyboard is used to add buttons to a chat with a user. Just create a Button class and provide text (The text on the button). You can provide phrase for fast binding to the processing function, or you can provide any callback_data to a Button and it will be returned on Message class in callback_data.

btn = Button(text="My button", phrase="/data", callback_data={"foo": "bar", "bar": "foo"})
bot.send_message(message.user.login, "Select an action", inline_keyboard=[btn])

Handling next step

For example, to wait for a response from a user to a question, you can use bot.register_next_step_handler. This method will store the session with the current user. The method includes:

1. user_login - the username of the user from whom to wait for the message;
2. callback - the handler function

@bot.on_message(phrase="/name")
def get_user_name(message):
    bot.send_message(message.user.login, "Type your name")
    bot.register_next_step_handler(message.user.login, type_your_name)

def type_your_name(message):
    bot.send_message(message.user.login, f"Your name is {message.text}")
