How to upload a photo to Instagram using request post python?

My code for login:

import re
import requests

from datetime import datetime

link = 'https://www.instagram.com/accounts/login/'
login_url = 'https://www.instagram.com/accounts/login/ajax/'
user_name = ****
password = ****

time = int(datetime.now().timestamp())
print(time)
payload = {
    'username': user_name,
    'enc_password': f'#PWD_INSTAGRAM_BROWSER:0:{time}:password',
    'queryParams': {},
    'optIntoOneTap': 'false'
}

with requests.Session() as s:
    r = s.get(link)
    a = r.cookies['csrftoken']
    print(a)
    csrf = re.findall(r"csrf_token\":\"(.*?)\"", r.text)[0]
    print(csrf)
    r = s.post(login_url, data=payload, headers={
        "User-Agent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36",
        "X-Requested-With": "XMLHttpRequest",
        "Referer": "https://www.instagram.com/accounts/login/",
        "x-csrftoken": csrf
    })
    print(r.status_code)
    print(r.url)
    print(r.text)
    print(s.cookies)
    r = s.get('https://www.instagram.com/accounts/edit/')
    print('user_name' in r.text)
