How to create FSM in aiogram correctly?

Question

Python

I need to set states to numbers that the user will enter. But I don't know in advance how many numbers will be entered. Two, three, maybe ten. How to implement fsm in this case?

Answer 1

Make one state that accepts numbers. Tired of accepting - we complete

class Form(StatesGroup):
    number = State()

@dp.message_handler(state=Form.number)
async def process_number(message: types.Message, state: FSMContext):
    if message.text != “0”:
        await message.reply(message.text)
    else:
        await state.finish()
