Why does sqlite3 output empty square brackets, +aiogram?

Question

Python

I am writing a bot for a telegram, I ran into a problem that empty square brackets are displayed when querying the database

@dp.message_handler(content_types=['text'])
async def profile(msg: types.Message):
    if msg.text.lower() == "профиль":
        cursor.execute("SELECT * FROM users WHERE chat_id = '{msg.chat.id}'")

        data = cursor.fetchall()
        print(data)

Answer 1

Problem already fixed

@dp.message_handler(content_types=['text'])
async def profile(msg: types.Message):
    if msg.text.lower() == "профиль":
        cursor.execute("SELECT * FROM users WHERE chat_id = '{msg.chat.id}'")
        for value in cursor.execute(f"SELECT * FROM users WHERE chat_id = '{msg.chat.id}'"):
            print(value[0], value[1], value[2])
            await msg.answer(f"id: " + value[0] + "\n\n" + "Имя: " + value[1] + "\n\n" + "Баланс: " + str(value[2]))
