save document.cookie output in a file - python-3.x

Question

skillshare-downloader says:
grab your cookie by typing:
document.cookie
Then it says:
Copy-paste cookie from developer console (without " if present) into example script.
Example:
from downloader import Downloader
cookie = """
ADD YOUR COOKIE HERE
"""
It adds an extra step.
Is there any way we can save document.cookie output to a file so that we can just read the cookie from the file instead of going to the console and type document.cookie and copy-paste the output?
I checked How to write console.log to a file instead. I also checked Python open browser and run javascript function. It suggests using Selenium or webbroser module. However, I am not sure how to approach this problem.
What can I do?

Answer 1

Assuming that you are using chrome:
Install selenium by running in a terminal pip install selenium
Install a chromedriver via a manager (It allows you to control chrome) by running in a terminal pip install webdriver-manager
Create a file example.py and paste this inside
#import the selenium webdriver and the chromedriver
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from time import sleep
#trying to stop skillshare from detecting we a are a bot
options = webdriver.ChromeOptions()
options.add_argument('--disable-blink-features=AutomationControlled')
#create the instance of chrome
driver = webdriver.Chrome(ChromeDriverManager().install(),options=options)
#get command used to open an url
driver.get('https://www.skillshare.com/')
#login part
#press on sign in
driver.find_element_by_css_selector("a.button.alt-white-ghost.transparent.initialized").click()
#change email here
driver.find_element_by_name("email").send_keys("testmail#mail.com")
#change password here
driver.find_element_by_name("password").send_keys("fakepassword")
#wait a second
sleep(1)
#click on sign in
driver.find_element_by_xpath("//span[text()='Sign In']/parent::button").click()
#wait 3 seconds for the login
sleep(3)
#execute_script is used to execute the command in the browser console, using return here to store it in a variable
cookie = driver.execute_script('return document.cookie')
#python way of creating a file on the given path and write the cookie inside it
f = open("D:\cookie.txt", "w")
f.write(cookie)
f.close()
#closing the chrome instance
driver.close()
open a terminal and type python example.py and it will run the script
