How to get page source in Selenium?

When web scraping, we often want to retrieve full page source (full HTML of the web page) we can parse it for data using tools like BeautifulSoup. Using Python and Selenium, to get the page source we can use driver.page_source attribute:

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://httpbin.dev/html")
print(driver.page_source)

⚠ It's possible that this command will retrieve page source before the page fully loads if it's a dynamic javascript page. For more see How to wait for page to load in Selenium?
