How to login to a website and scrape data using python

Try using mechanical soup. It allows you to navigate a website just like you would normally.

As pointed out in the comments, a possibility is to use selenium, a browser manipulation tool. However, you can also use requests.Sessions to send a POST request with a payload of the email, and then a GET request for whatever portal page you wish to view after:

import requests
r = requests.Session()
payload = {'portalAccountUsername':'[email protected]'}
r.post('https://hac.chicousd.org/LoginParent.aspx?page=Default.aspx', data = payload)

Then, with r instance, you can send a GET request to a page on the portal that is only visible to authenticated users:

data = r.get('https://hac.chicousd.org/some_student_only_page').text

Note that the keys of the payload dictionary must all be valid <input> "name" values from the site's HTML.

As others have said, you can use selenium. You also should use time to stop the program some seconds before to put your password. First install selenium in you command prompt pip install selenuim and a webdriver (here is the code for chrome pip install chromedriver_installer). Then you could use them in your code.

import selenium
from selenium import webdriver
import time
from time import sleep

Then, you should open the web page with the web driver

browser = webdriver.Chrome('C:\\Users...\\chromedriver.exe')
browser.get('The website address')

The next step is to find the name of the elements on the web page to write your username, password, and the path for the buttons

username = browser.find_element_by_id('portalAccountUsername')
username.send_keys('your email')

next = browser.find_element_by_xpath('//*[@id="next"]')
next.click()

password = browser.find_element_by_id('portalAccountPassword')
time.sleep(2)
password.send_keys('your password')

sing_in = browser.find_element_by_xpath('//*[@id="LoginButton"]')
sing_in.click()
