This code for Telegram bot suposse to work because I copyed it, but does not – Telegram API

I started learning making bots in Telegram with Python 3. I was learning it by this course https://groosha.gitbook.io/telegram-bot-lessons/. In a lesson 2 there was a code 

    import telebot

    bot = telebot.TeleBot(config.token)

    @bot.message_handler(commands=['test'])
    def find_file_ids(message):
        for file in os.listdir('music/'):
            if file.split('.')[-1] == 'ogg':
                f = open('music/'+file, 'rb')
                msg = bot.send_voice(message.chat.id, f, None)
                bot.send_message(message.chat.id, msg.voice.file_id, reply_to_message_id=msg.message_id)
            time.sleep(3)


    if __name__ == '__main__':
        bot.polling(none_stop=True)

and it must work like: I put some audio files in the music folder, and then the bot sends to me the audio id.
But when I copy this code, I am getting the same error every time:

2020-01-30 19:16:09,945 (util.py:66 WorkerThread2) ERROR - TeleBot: "NameError occurred, args=("name 'os' is not defined",)

    for file in os.listdir('music/'):

What am I supposed to do?

    As the interpreter said, you are using os module’s function without importing it. You have to import it at the top of your code, like

    import os
import telebot

    You’re missing an import os statement at the top of your code.
