In this article, we are going to see how to control the web browser with Python using selenium. Selenium is an open-source tool that automates web browsers. It provides a single interface that lets you write test scripts in programming languages like Ruby, Java, NodeJS, PHP, Perl, Python, and C#, etc.
To install this module, run these commands into your terminal:
pip install selenium
For automation please download the latest Google Chrome along with chromedriver from here.
Here we will automate the authorization at “https://auth.geeksforgeeks.org” and extract the Name, Email, Institute name from the logged-in profile.
Initialization and Authorization
First, we need to initiate the web driver using selenium and send a get request to the url and Identify the HTML document and find the input tags and button tags that accept username/email, password, and sign-in button.
To send the user given email and password to the input tags respectively:
driver.find_element_by_name('user').send_keys(email) driver.find_element_by_name('pass').send_keys(password)
Identify the button tag and click on it using the CSS selector via selenium webdriver:
driver.find_element_by_css_selector(‘button.btn.btn-green.signin-button’).click()
Scraping Data
Scraping Basic Information from GFG Profile
After clicking on Sign in, a new page should be loaded containing the Name, Institute Name, and Email id. Identify the tags containing the above data and select them.
container = driver.find_elements_by_css_selector(‘div.mdl-cell.mdl-cell–9-col.mdl-cell–12-col-phone.textBold’)
Get the text from each of these tags from the returned list of selected css selectors:
name = container[0].text try: institution = container[1].find_element_by_css_selector('a').text except: institution = container[1].text email_id = container[2].text
Finally, print the output:
print({"Name": name, "Institution": institution, "Email ID": email})
Scraping Information from Practice tab
Click on the Practice tab and wait for few seconds to load the page.
driver.find_elements_by_css_selector('a.mdl-navigation__link')[1].click()
Find the container containing all the information and select the grids using CSS selector from the container having information.
container = driver.find_element_by_css_selector(‘div.mdl-cell.mdl-cell–7-col.mdl-cell–12-col-phone.whiteBgColor.mdl-shadow–2dp.userMainDiv’)
grids = container.find_elements_by_css_selector(‘div.mdl-grid’)
Iterate each of the selected grids and extract the text from it and add it to a set/list for output.
res = set() for grid in grids: res.add(grid.text.replace('\n',':'))
Below is the full implementation:
Python3
# Import the required modules from selenium import webdriver import time # Main Function if __name__ = = '__main__' : # Provide the email and password email = 'example@example.com' password = 'password' options = webdriver.ChromeOptions() options.add_argument( "--start-maximized" ) options.add_argument( '--log-level=3' ) # Provide the path of chromedriver present on your system. driver = webdriver.Chrome(executable_path = "C:/chromedriver/chromedriver.exe" , chrome_options = options) driver.set_window_size( 1920 , 1080 ) # Send a get request to the url time.sleep( 5 ) # Finds the input box by name in DOM tree to send both # the provided email and password in it. driver.find_element_by_name( 'user' ).send_keys(email) driver.find_element_by_name( 'pass' ).send_keys(password) # Find the signin button and click on it. driver.find_element_by_css_selector( 'button.btn.btn-green.signin-button' ).click() time.sleep( 5 ) # Returns the list of elements # having the following css selector. container = driver.find_elements_by_css_selector( 'div.mdl-cell.mdl-cell--9-col.mdl-cell--12-col-phone.textBold' ) # Extracts the text from name, # institution, email_id css selector. name = container[ 0 ].text try : institution = container[ 1 ].find_element_by_css_selector( 'a' ).text except : institution = container[ 1 ].text email_id = container[ 2 ].text # Output Example 1 print ( "Basic Info" ) print ({ "Name" : name, "Institution" : institution, "Email ID" : email}) # Clicks on Practice Tab driver.find_elements_by_css_selector( 'a.mdl-navigation__link' )[ 1 ].click() time.sleep( 5 ) # Selected the Container containing information container = driver.find_element_by_css_selector( 'div.mdl - cell.mdl - cell - - 7 - col.mdl - cell - - 12 - col - phone.\ whiteBgColor.mdl - shadow - - 2dp .userMainDiv') # Selected the tags from the container grids = container.find_elements_by_css_selector( 'div.mdl-grid' ) # Iterate each tag and append the text extracted from it. res = set () for grid in grids: res.add(grid.text.replace( '\n' , ':' )) # Output Example 2 print ( "Practice Info" ) print (res) # Quits the driver driver.close() driver.quit() |
