How to add emoji to menu in telegram bot python?

you can add emoji in the same place where you add text

telegram.KeyboardButton(text="Hello ")

You can write down user_keyboard_markup() function and use it to display with each message you send. You can generate different functions to display different content depending on what users choose. You need just add reply_markup=... to your message.

my_markups_folder/markups.py:

def user_keyboard_markup():
    user_markup = ReplyKeyboardMarkup(True, True)
    button_site = KeyboardButton(text="Web site ")
    
    user_markup.row('/start', '/help', '/stop')
    user_markup.row('', '', '')
    user_markup.add(button_site)
    return user_markup

def my_other_keyboard_markup():
    return None

main.py:

...
from my_markups_folder.markups import user_keyboard_markup

...

@bot.message_handler(content_types=['text'])
def handle_text(message):
    if message.text == "show me keyboard markup":
        
        bot.send_message(message.from_user.id,
                         text=f"""
        *Motpheus:*
        Welcome back, Neo!
        """, parse_mode='markdown', reply_markup=user_keyboard_markup())
