// Source: https://localcoder.org/get-csrf-token-using-python-requests

//Solution 1: 
from bs4 import BeautifulSoup
soup = BeautifulSoup(response.text, 'lxml')
csrf_token = soup.select_one('meta[name="csrf-token"]')['content']

// Solution 2: 
import requests
from bs4 import BeautifulSoup
headers = {'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 
           (KHTML, like Gecko) Chromium/80.0.3987.160 Chrome/80.0.3987.163 
           Safari/537.36'
 }
login_data = {
             'name' : 'USERNAME',
             'pass' : 'PASSWORD',
             'form_id':'new_login_form',
             'op':'login'
  }

with requests.Session() as s:
    url = 'https://www.codechef.com/'
    r = s.get(url,headers=headers,verify=False)
    #print(r.content) # to find name of csrftoken and form_build_id
    soup = BeautifulSoup(r.text, 'lxml')

    csrfToken = soup.find('input',attrs = {'name':'csrfToken'})['value']
    form_build_id = soup.find('input',attrs = {'name':'form_build_id'}) 
    ['value']

    login_data['csrfToken'] = csrfToken
    login_data['form_build_id'] = form_build_id

    r = s.post(url,data=login_data,headers = headers)
    print(r.content)
