Why is Dispather needed in Aiogram?

Question

Python

The code:

bot = Bot(token = TOKEN)
mybot = Dispatcher(bot) 

@mybot.message_handler(commands = 'start')
async def greetings(message: types.Message):
  stick = open('settings\\Greetings_from_Steve_Jobs_for_users_of_my_second_python_bot_for_telegram.webp', 'rb')
  await bot.send_sticker(message.chat.id, stick)
  stick.close()

What is the Dispatcher for, if sending is done like this: await bot.send_sticker(message.chat.id, stick)?

Also, why open a file in binary mode?

Answer 1

It is not necessary to go so deep at this stage of studying the library.
In short Dispatcher accepts all updates and processes them.
You can send messages as you like, even await mybot.bot.send_sticker or await bot.send_sticker, as long as everything is imported correctly
