Photo upload error?

Question

Python

Here is my program:

def adc_2(message):
    bot.send_photo(config.worker, message.photo[0].file_id)
    bot.send_message(message.chat.id, mess1, reply_markup=keyboard)
    bot.register_next_step_handler(message, menu)

Here is the error

Mistake

Process finished with exit code 1

This program is like an echo bot, it only sends the photo not to the person who just sent it, but to the person whose ID is config.worker what is the error

Answer 1

There is nothing in message.photo, so this error occurs. Wrap this line in the condition that message.photo is a list.

Explanation

Скорее всего, эта функция вызывается при каждом событии "Получение сообщения", содержит ли тело сообщения фотографии или нет. И, если фотографий нет, то в message.photo тоже, разумеется, ничего нет и его тип соответствует NoneType. При попытке взять значение из такой переменной, как из списка, выполняется ошибка TypeError.

if type(message.photo) is list
