How to send a photo via telegram api?

Question

Python

Good afternoon.
I'm trying to teach a bot to send photos.

def send_photo(chat_id, photo):
    url = URL + 'sendPhoto'
    answer = {'chat_id':chat_id, 'photo':photo}
    r = requests.post(url, json=answer)
    return r.json()

f = open("C:\\Python37\\project\\photo\\1.jpg", 'rb')
send_photo(chat_id, f)

Python throws an error:
TypeError: Object of type BufferedReader is not JSON serializable
What am I doing wrong?

Answer 1

What library are you using?
import telebot
from telebot import types
img = open(imageFile, 'rb')
bot.send_photo(chatID, img, caption=TEST)
