<html>
<head>
    <title>The Dormouse's story</title>
</head>
<body>
    <p class="title"><b>The Dormouse's story</b></p>
    <p class="story">Once upon a time there were three little sisters; and their names were
    <a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,
    <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and
    <a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>;
    and they lived at the bottom of a well.</p>
    <p class="story">...</p>
</body>
</html>
"""

soup = BeautifulSoup(html_doc, 'html.parser')

# Print the title of the document
print(soup.title.string)

# Find and print all links
for link in soup.find_all('a'):

pip install selenium

You will also need to download the appropriate WebDriver for the browser you want to use (e.g., ChromeDriver for Chrome, GeckoDriver for Firefox).

Basic Usage:

Here’s a basic example of how to use Selenium to open a web page, interact with elements, and extract data:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Initialize the WebDriver (e.g., Chrome)
driver = webdriver.Chrome(executable_path='/path/to/chromedriver')

# Open a web page
driver.get("http://www.example.com")

# Find an element by ID and interact with it
search_box = driver.find_element(By.ID, "search")
search_box.send_keys("Selenium")
search_box.send_keys(Keys.RETURN)

# Wait for a specific element to be present
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "result"))
    )
finally:
    driver.quit()

# Extract information
print(element.text)
