How to save Audio to a variable?

Question

Python

Hello, this is the case, so I decided to put the bot into a cart, and now I need the bot to receive the audio message and save it to a variable for further work with it, that's what happened to me, but I can't output the data from the variable to another functions.

@bot.message_handler(commands=['start'])
def handle_message(message):
    sent = bot.send_message(message.chat.id, 'Пришлите аудио файл :')
    bot.register_next_step_handler(sent, save_link)
def save_audio (message):
    sent = bot.send_message(message.chat.id, 'Введите текст под аудио :')
    audio = message.audio.file_id
    bot.register_next_step_handler(sent, audio_description)
def audio_description(message):
  bot.send_audio(message.chat.id, audio)

Answer 1

You can pass additional parameters

bot.register_next_step_handler(sent, audio_description, audio)
...
def audio_description(message, audio):

Answer 2

And is it intended that you pass the save_link function to register_next_step_handler , and you have the save_audio function declared ?
