Changing the photo in the message by pressing the inline button Aiogram

Question

The bot parses data from the site and writes everything to the list. I want to show the next photo from the above list every time I click "next" button.

from aiogram import Bot, types
from aiogram.dispatcher import Dispatcher
from aiogram.utils import executor
from aiogram.types import InlineKeyboardMarkup, InlineKeyboardButton, InputMedia


poster = ['any url photo', 'any url photo', 'any url photo']


next_btn = InlineKeyboardButton(text='next', callback_data='next')

neBTN = InlineKeyboardMarkup()
neBTN.add(next_btn)


@dp.message_handler(commands=["start"])
async def photo(message: types.Message):
    file_path = poster[1]
    reply_markup = neBTN

    await bot.send_photo(
        message.chat.id,
        photo=file_path,
        reply_markup=reply_markup,
        caption="Test caption!",
    )


@dp.callback_query_handler(text="next")
async def photo_update(query: types.CallbackQuery):
    file_path = poster[2]
    reply_markup = neBTN
    file = InputMedia(media=file_path, caption="Updated caption :)")

    await query.message.edit_media(file, reply_markup=reply_markup)

I just started working closely with the Python programming language and decided to try to create a bot, but I ran into a problem that I can not solve. I tried to go through the for loop, but it turns out somehow badly, by clicking all the photos quickly change to the last one from the list.

Try to use InputMediaPhoto() instead of InputMedia().

from aiogram import Bot, types
from aiogram.dispatcher import Dispatcher
from aiogram.utils import executor
from aiogram.types import InlineKeyboardMarkup, InlineKeyboardButton, InputMediaPhoto
from dotenv import load_dotenv

# Import module to create an iterable object
from itertools import cycle
import os

load_dotenv()
TOKEN = os.getenv("TOKEN", "")
bot = Bot(TOKEN)
dp = Dispatcher(bot)

poster = [
    "https://pic.rutubelist.ru/video/17/b1/17b100a0bcbc6e5e8d11101cde21aca7.jpg",
    "https://funik.ru/wp-content/uploads/2018/10/6db3f15d0a21589aaa1b.jpg",
    "https://psihoman.ru/uploads/posts/2022-02/1645693727_1645693779.jpg",
]
next_btn = InlineKeyboardButton(text="next", callback_data="next")
# Thats create an iterable object of our list of links or paths
cycle_poster = cycle(poster)

neBTN = InlineKeyboardMarkup()
neBTN.add(next_btn)


@dp.message_handler(commands=["start"])
async def photo(message: types.Message):
    # iteration
    file_path = next(cycle_poster)
    reply_markup = neBTN

    await bot.send_photo(
        message.chat.id,
        photo=file_path,
        reply_markup=reply_markup,
        caption="Test caption!",
    )


@dp.callback_query_handler(text="next")
async def photo_update(query: types.CallbackQuery):
    file_path = next(cycle_poster)
    reply_markup = neBTN
    file = InputMediaPhoto(media=file_path, caption="Updated caption :)")

    await query.message.edit_media(file, reply_markup=reply_markup)


if __name__ == "__main__":
    executor.start_polling(skip_updates=True, dispatcher=dp)

That's not the point at all. The problem lies, so to speak, in "switching" between the list items at the touch of a button. To take the next item in the list. — Pizza_Chicago, Jan 13 '23 at 16:38
