How to handle cookies in the Selenium web driver using Python

Selenium is a Python automation module used to automate and test web applications. In this answer, we'll learn to handle cookies in Selenium using Python.

Cookies are files that contain small pieces of data sent by the server to the web browser. We can store, retrieve, delete, and list cookies using the below methods:

add_cookie(): We can add a cookie using this method.
get_cookies(): It is used to list all cookies.
get_cookie(): It is used to get only one cookie based on its name.
delete_cookie(): It is used to delete a cookie based on its name.
delete_all_cookies(): It is used to delete all the cookies.

Code example

Let’s look at the example below:

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
import time
 
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
prefs = {"download.default_directory": "."}
options.add_experimental_option("prefs", prefs)

#get instance of web driver
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)

#provide website url here
driver.get("https://omayo.blogspot.com/")

# add cookies
driver.add_cookie ({ 'name' : 'firstname', 'value' : 'James'})
driver.add_cookie ({ 'name' : 'lastname', 'value' : 'xyz'})

print("---List of cookies after adding all cookies---")

# get all cookies
print(driver.get_cookies())

print("---Display cookie which has name as firstname---")

# get cookie with its name
print(driver.get_cookie('firstname'))

# delete cookie
driver.delete_cookie('lastname')

print("---List of cookies after deleting one cookie---")
print(driver.get_cookies())

#delete all cookies
driver.delete_all_cookies()

print("---List of cookies after deleting all cookies---")
print(driver.get_cookies())


time.sleep(10)

Code explanation

Line 14: We create an instance of a web driver and assign it to a variable driver.
Line 17: We open the web page using the get() method.
Lines 20–21: We add cookies to the current webpage using the add_cookie() method.
Line 26: We list all the cookies present using the get_cookies() method. It will return a list of cookies as a list of dictionaries.
